Head work

Lookin at getting some head work done. Like porting polishing and shaving. I have factory e7 heads. I want gt40p cuz I know there better. I'm on a budget tho and I want to get this all done as soon as possible. I'm just wondering how much better the gt40s are. If I had worked e7s?

The e7s will barely, if any outflow gt40s after worked.

If your looking for good hp then find some good aluminum heads. If your strickly budget a gt40 swap maybe cheaper than working the e7s.

Over stock the gt40s can see about 20-40hp with supporting mods.

A good set of aluminums can see up to 100+ hp with supporting mods.

8-1200$

But if you can't fork that keep watching eBay, craigslist etc. But buyer beware. I've seen some people score some good deal.

A whole lot. Those heads are Awsome. You would probably be pretty impressed.
The only problem is the may require knotching the pistons.

The afr 165s don't require knotching the pistons. and you would still see great gains. But if your motor is stroked you probably want heads comparable to the 185s.

yeah i was reading about 347stroker motors and everyone says gt40 heads arent a good choice so im putting money aside for afr 185s what else heads are close to as good as afr 185s but maybe not as pricey

Trickflow heads usually have more clearance. I would look into the 185 or 205 from either brand. And also its hard to say what clearances you will have. It would help to know what pistons you have. But when doing a head swap, you can't ever be sure what piston to valve clearance you gonna have to you check.
