Re: Heads for a 350 chevy
Ditto on the Vortecs. You will never find a better bang for the buck, EVER! You have to run a Vortec style intake which is available from every manufacturer and also centerbolt valve covers. Dont let the valve size fool you. They flow well.

Re: Heads for a 350 chevy
I would go to a local engine shop and find some rebuild stock 305 heads that are 64 cc, with the largest valve they have and buy them. For about $200, you will really wake your truck up. This will bump your compression over 10:1.

Re: Heads for a 350 chevy
Check Competition Products Web Site for Dart Iron heads I think you can buy them cheaper than vortecs and they are very nice . They are priced depending on what you want . The bigger and badder you want the more money you spend . You don't have to run a vortec intake either . My 2 Cents . Bob

I would also agree with vortec heads! All day long the best bang for your buck. And if yo don't like centerbolt heads, no worries. They have an adapter so you can run your regular side bolt valve covers. JMHO. SHawn

Re: Heads for a 350 chevy
I put a pair of Summit brand heads on my 350 in my 'burb. The day after I got back from B'ville this summer white smoke came out of the right bank, it was a cracked head. They were double humps and it was more reasonable to replace them with the Summits that find a head and have them both completely redone. I drive my 'burb daily and they seem to be working well.

Re: Heads for a 350 chevy
It depends on what you want to spend, and what is in your engine right now. I say if it is mildly hopped up go with stock 64cc 305 heads if you are on a budget. Thats what I have and I still managed to run a 13.8 sec 1/4 mile. If you have the extra money go with the world product heads, there going to be better. Just my .02

Re: Heads for a 350 chevy
By the time you get the heads machined for screw in rocker studs, machined spring pockets for bigger springs and valves and a valve job (assuming you don't want to stick with the 1.94"/1.50") its better to go with Dart Iron Eagles. They will cost around $950 for a complete set with your spring choice and choice of valves 2.02 or 2.05 .
My car with a roller cam and these heads untouched puts down 350hp to the wheels. |

Re: Heads for a 350 chevy
For the record guys, 305 have heads do not have 64cc chambers. They range from 58cc - 60cc chambers. Companies like Aerohead and others enlarge the chambers with valve deshrouding cutters and make them 64cc but they come from the factory smaller. The run-on problem they are notorious for is due to a small chamber with severely shrouded valves that create excessive heat. This causes the "dieseling" effect. If the timing is kept on the low side they do perform OK on a 350, but unless I was on a shoestring budget and had them laying around, I'd go another route. I've ran them in past on 327's and 350's with pretty good results, but I wouldn't buy a set and spend money on valve job when Vortecs and others can be bought so reasonably. They actually work really well on a 307 though...

![]() I'm building an engine for my red '69 right now, and its going to be strictly a daily driver, but I do want more power than the 76cc headed smog 350 has that's in it now. I'm basically building a carb'd version of the GMPP Ram Jet 350. It's a going to be a 4 valve relief flattop .030" 1 piece seal 350 with Vortecs and Ram Jet hydraulic roller P/N 14097395. It is a mild, smooth idling cam but makes great torque and very good HP for what it is. This is a proven combination, and I know it will make my truck much more fun to drive. With the same heads and cam and 9.4 CR, the Ram Jet 350 is advertised at 350HP and 400ft lb. I'm going to be running an dual plane aluminum intake and Q jet with ram horns and 2.5" duals, so I won't quite make those numbers, but it will be very stout nonetheless.

Re: Heads for a 350 chevy
I am a big fan of dart, plus thumbs up on made in America, I would rather have a slower ride and keep some slub here working rather then go fast and keep some party boss in China slurping down eel eyeballs. Personally, I would buy a used set, guys are getting rid of extra go fast parts now for money to pay the rent.

Hard to beat the Vortecs.
Here's a link to get the kit to change over. With Edelbrock Performer intake: http://paceperformance.com/index.asp...D&ProdID=73011 With Edelbrock Performer RPM intake: http://paceperformance.com/index.asp...D&ProdID=18329 Of course if you need everything for the top end: http://paceperformance.com/index.asp...&ProdID=219069

Re: Heads for a 350 chevy
new vortech heads with a 5 angle valve job and screw in rocker studs, wich you'll need when crossing over the .500 in lift. https://www.patriot-performance.com/...ome.php?cat=76
These heads are tapped for the old andnew type intake manifold, also perimeter v/c or centerbolt v/c.
