I am working on an l33 procharger build. I have 2 choices of heads. 241 or 317. From what I understand 241 would make it 10:1 and 317 would make 9.5:1. I am planning on making 600-700 rwhp. What should I do? Fuel will be e85 or 91 with meth.

10:1 compression.

Why did you get away from the stock 243/799's?

Bought a short block. No heads . Would it be worth getting some ported heads from Texas speed?

That's up to you. Typically any gains seen in NA form will be translated to boosted performance.

Ok thanks. What's best e85 or 91 with meth ?

Pump and meth will do.
