Engine finally in! What headers fit?

[David67]

Ok well I finally got the engine in and need to find some headers. Has anyone tried these and know if they fit? If not, what do yall have that fits?

Summit branded headers carry part numbers that correspond to Flotech. There have been other posters on here who have used them and been satisfied. The price is decent.

The flowtechs fit like a surgical glove. Install pass side from top and drivers side from bottom. You might be able to do it from the top if spark plugs are out.

Also get rid of that fram filter. I'd find a Baldwin filter or even the napa gold.

thanks for the info! yea those plugs are old ones that were in there for painting. Do yall know if there's any problems with warping and leaking or is 5/16 a good flange thickness?

[Beat68CST]

My dad used to do exhausts for a living, we still build headers and exhaust systems from time to time, he says 3/8's minimum.

[David67]

Ok the others that I'm looking at are the ceramic coated ones from LMC. I see these have 3/8 flanges, 1-5/8 primary tube, 3" collectors, and happen to come with all hardware/gaskets.

I like how the LMC ones have 3/8 flanges but I've heard that in some cases its better to have smaller tubes. Has anyone used these or have any advice?

David67 coming out very nice.

Looks good ! One thing Get ride of that FRAM !

I have Flowtech on my big block in my thread. Check em out. I'm pretty happy with them overall. The finish on the ceramic ones is not perfect, but they're not $500-600 like the Headmans. I guess it just depends on what you're looking for and budget.

Nothing wrong with my Flowtechs so far. $265 from Summit. If they discolor, or rust up I'll re-evaluate then.

That engine looks nice When I bought my headers they reccomended not to break in the engine with them on because the coating may become discolored or something. I believe it voids the warranty on the coating. Mine are black not ceramic but it was the same for ceramic or black. According to the application chart on the link they will fit. I can't tell how low your truck is, but full length headers hang below the frame rails If it is real low you may scrape alot at the collectors... just my .02 cents.

Yea those look sweet! They're kinda like the bb versions of the ones I'm looking at. I'm definitely not looking for a $500-600 pair of headers and those look pretty good. I was also just looking into radiators and came across one by Be Cool...is that what you're running? It says the dimensions are 34x19x3 and I'm pretty sure it'll fit but not 100%...plus I'm not sure if I want to go with an aluminum one since they're more $$$

Looks good, keep up the good work!

Thanks a lot which ones did you go with? And I'm running a 4/6 so that shouldn't be an issue.

The smaller primaries will usually produce more lowend torque, while the larger primaries produce more top end hp.

I know you want the thicker flange, but the 1 1/2 primaries are better suited for a near stock motor.

I often thought of making 1-3/8 headers for my own truck.

Here is something to play with-

David67,
I went with Hookers They are 1 5/8" primaries. I dont quite remember the flange thickness. Those seem like a good deal though. I cant wait to see the installed pics

Cool! I've been leaning towards the summit ones and I'm going with those. I might initially have on the stock manifolds if theres an issue with engine break in...

I think so too. ME NEITHER!

I should have my ignition coil, headers, air cleaner, and Holley 600 carb by next week sometime!

[David67]

I just realized something that I should've thought of earlier. I have Vortec heads. Will they still fit?

[barry h.]

I user summit coated and they look and fit very well for like $220.00

Sorry about hijacking.... But for those saying to get rid of the Fram filters>

I know that there's a lot of controvery regarding the quality of the filters but I've been using them for 20 plus years with no problems. I change the oil between 3k and 5k and so far 4 of the vehicles I've had that I regularly used the Frams on had well over 200K miles on the engine before I traded them in. Only my 87 olds Calais had an engine problem. The non metal cam gear went out at around 220K. Maybe I've been lucky.

[Clyde65]

I have Sanderson headers and I really like them, might be a bit more $ but they dont need gaskets and they came coated, still look very nice, like new.

[VWBeamer]

The bashing comes with merit, several have cut them open and compared them to other brands. The Fram consistently does poorly in such comparisons.

If you google you can find more reviews, and it's easy to see why the Fram is generally not well regarded.

EDIT: wanted to add this letter, even the Fram engineers say Fram is not very good.

Hi jack over.

Thanks. I have read some of the write-ups but I just wanted to give another side to the story.

Again, sorry for hijack...

[sleepertruck72]

David,
I dont think you should have a problem with the headers fitting the Vortec heads. I have vortec heads and my headers fit fine. To be sure you might want to call Summit Customer Service and ask. I did before ordering mine and they assured me they would fit.
