Re: Restoring Rusty
WHO LET THE WIFE INTO THE WORKSHOP? - Honey put the camera down and slowly back away. not only do I do all the work myself, but I also do all my own stunts!
TOP TIP: don't just spin the drill while pulling on it, move the drill in and out so it raises the valve and falls back into the seat getting a good contact each time Last edited by Gregski; 03-19-2016 at 02:15 AM. |

Re: Restoring Rusty
the tube of gunk you put on the valve says use liberal amount, so I did
whats the motor oil for Greg? I use the motor oil on the valve stem so it don't rub metal on metal in the valve guide, this is some oil I happen to have for my wifes plastic Honda Pilot, I would have prefered some with some Zinc in it, but shhhh don't tell Last edited by Gregski; 03-19-2016 at 02:10 AM. |

Re: Restoring Rusty
OK, so since this has literally been my first Rodeo, I took it nice and easy, I decided to do the exhaust valves first as they needed it most, and I ground each a bit and stopped and took them out and examined them, so the first pic is of a valve about half way done, the second pic is aftet I put it back in and ground it some more, and the third pic when it was done, better safe than sorry
IMPORTANT, when you run the drill run it both ways, a little bit forward and than reverse direction just wanted to show you the progression, and then the last shot is a stare and compare of how the valve starts out looking compared to one that has been lapped Last edited by Gregski; 03-19-2016 at 02:14 AM. |

Re: Restoring Rusty
now the valves aint the only thing getting smoother and less shinny, that would be like clapping with one hand, the valve seats are getting some grindage love too
I am beginning to realize that as much as we like the bits on the outside of the motor to be shinny, they actually prefer to be a bit dull on the inside, (think honed cylinders) am I right Master Machinists? here is a not lapped valve seat (shinny mirror like finish) compared to a lapped one (dull) This is looking good, Man I tell you this truck is going to be the fastest "Drop Your Kid At Piano Lesson" Truck in town. |

Re: Restoring Rusty
now onto the intake valves, these in my opinion didn't need as much grindage so I took it easier
pic 1 - first intake valve done pic 2 - a little before and after stare and compare |

Re: Restoring Rusty
look more parts, I think all the big stuff is here now, I may be missing some gaskets, a belt, and a freeze plug or two, but I can get that stuff locally
SERIOUSLY Greg? We're going to get there one bolt at a time? No, ha ha, I had to buy one bolt because the other lot came with like 15 or something and I needed a total of 16 of course the Timing Set is from an outfit called GM Parts Direct, seemed to have the parts that Summit and JEGS let me down on Last edited by Gregski; 03-19-2016 at 02:04 AM. |

Re: Restoring Rusty
yeah I decided to buy brand new head bolts, my daddy if he was a car guy I'm sure would say "son you never wanna reuse old head bolts" needless to say I bought these bad boys from privateers no eBay
all together there be: 16 - short ones 7/16-14 x 1-3/4" GM part number 10168527 14 - long ones 7/16-14 x 3-13/16" GM part number 10168525 4 - medium ones 7/16-14 x 3-1/16" GM part number 10168526 I'm not sure many people know this, but when GM designed the Vortec cylinder heads they had two goals: 1. Design the best flowing iron heads they could. 2. Use up their surplus of head bolts, ie 17 per head |

While I'm on the subject of grinding stones. I've had the Asian cheapies that came with one of my newer bench grinders explode. It tore the sheet metal guard right off the motor. I'm real careful of them now. Even US made stones can do that if they are damaged.

Re: Restoring Rusty
Yup, that's the way they're supposed to look after lapping. Nice job!

Re: Restoring Rusty
My dad would steal (repurpose) my wooden arrows with the suction cups, cut 'em down and push 'em on the valve head side. He was a low budget master.

Re: Restoring Rusty
and now, an open letter to GM
3/20/2016 Anno Domini Dear GM Knuckleheads Please add basic arithmetic to the skill set required by your Accountant and Warehouse operator positions. You see you present common folk like me with a basic dilemma. A Small Block Chebby cylinder head you make requires 8 short bolts, yet you sell said bolts in packets of 5 (See peoples Exhibit 1A and 1B attached) This forces us to buy two baggies of bolts for a grand total of 10, that is two extra. What is a married man with children like me supposed to do with the two extra bolts, where do you expect me to store them in my stroller and bicycle and roller blade filled garage? My wife already expects to park her air conditioned, seat warmer, rear view camera vehicle in said WORKSPACE. Add to that the fact that in most cases you will be a replacing both heads, now the problem DOUBLES. Now you need 16 bolts but three baggies will only yield you 15 (again 5 per bag) man you are one bolt short, do you reuse one old bolt, can you discriminate one bolt hole like that and risk public humiliation when your car buddies realize what you have done. Oh no GM, you have to now purchase 4 bags of bolts, and have a total of 20, where you only need 16. Still with me GM? Now did you realize that manufacturing these 4 extra not needed bolts contributes directly to Global Warming [ahem] Climate Change! And every time you force us to buy them another tree hugger has to go out and buy yet another Prius. And does the fast lane on any highway need another _ _ _ _ _ _ _ Prius in it? So please get it right, and I know it will be a major paradigm shift, but sell them in fours in each bag, the entire SBC community will thank you and you will be making this world a better place you greedy _ _ stards. All My Love, The Greg P.S. Ah snap I just broke a head bolt while tightening it to spec, good thing I had some extras!!! Last edited by Gregski; 03-20-2016 at 10:58 PM. |

Re: Restoring Rusty
At least those headbolts come with pre-applied thread sealant... Not sure how much you want to trust it though.

So what is this White stuff? Honestly when I see it on bolt threads I can't help but think of what I call plumbers tape or teflon tape, technically called thread seal tape I guess. So please, learn me something. |

Re: Restoring Rusty
The head bolts thread into the water jacket, so they need a sealant to keep the coolant from wicking its way up the threads.
I use Permatex thread sealer on bolts, but yours come with the sealer already applied - saves a step!
