Be warned. Some of these products are NOT just bolt on. Bad valve seat work, tight valve guides, somewhat questionable pushrod clearances etc.


Might want to look to 440 source @ http://store.440source.com/440-Sourc...s/products/36/

You will still have to have them gone through to insure they are right.

This is for All New aftermarket heads!

Every New head you get should be gone through.

I strongly recommend finding a good performance machinist and ask they're opinion from they're experience with aftermarket aluminum heads. Whichever head you buy have them disassemble and completely inspect.

My son's Edelbrocks got the ok from my guy. Many now are buying the bare castings and having them built by a good machinist. If you search you tube you'll find problems with every manufacturers/suppliers head, this doesn't mean they are all bad but it is a chance you'll take with your newly rebuilt engine.
