Default What cr should I run?

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.

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.
