The set i have have been surfaced and mild pocket port done there are a small 58cc. and yes i will be running a dished piston. Im hoping for some awesome torque numbers and great fuel mileage. I guess we'll see how it goes.

Dont give up on that head just yet. I cant wait to get started on my engine. So keep us up to date on what you find.

Oh its just my opinion but I wouldn't run a edelbrock on anything. plus it might be to big. Im willing to bet if you got a smaller carb it would run better and accelerate better to. good luck to you

How would a smaller carb go faster? That makes no sense even 305s make more power with a 750 vs a 650. A cylinder head that is designed to help torque for a STREET car that's driven daily with a small cam and and small carb or injection would benefit. Otherwise in an out of stock application or anything that isn't trying to max you mpg on the street the heads are pretty much worthless.

So vortechs and zz4 l98 heads are about the best in terms of factory performance and price. The l98 head would be the best with the 58cc chamber and 175cc runners
