Yeah, I see the possibilities. Way more work and money than I want to invest in these heads. This combo is just a powerhouse that I have fun with on the street hitting T&T now and then. My goal while building this 511 was 700hp. Thought it would be close, but I choose the wrong cylinderhead. Had I known I would have bought the 440-1 or atleast a EZ head. Just looking for 700-750hp as a goal for now. I'm willing to invest $1000-$1500 into these, but any more and they go up for sale. Thanks again for the info guys. Its a constant learning curve.
