Thumper heads

Has anyone see or run e7 thumper heads with an f cam on a turbo car? Is it worth it or should I just wait and get a set or trick flow tw heads? Goal is for a 400-450 5 speed street car with a single 70mm.

The problem with E7 heads is their thin deck and chances of lifting. No amount of work done to an E7 is going to fix that issue.

That and they are iron.

Aluminum heads dissipate heat much faster and help reduce hot
spots in the combustion chamber and detonation.

HIGHLY recommend aluminum heads with any boosted motor. Is mo-betta

While that is true, I have ran iron heads with great success on my boosted cars and seen my friends do it as well. I would not go out and buy a new iron head these days but I would not hesitate one second to buy a used set that were nicely done up. I would do that because people have in their heads iron heads have very little value so they resale for cheaper than they should. For example my old Dart Sr heads which got several cars in the 10s and a couple in the 9s, all boosted cars, sold for WELL under $1k, actually did not sell for much more than what had been recently put in them for a valve job, guides and seals.

IF your only going for 400-450 hp it can be done with stock heads. however I would never suggest stock heads over TWs lol

NEVER do business with Sam Rivera AKA Sam Wilson.
