Cylinder head discussion 340 with stock above deck pistons

2.0 60' 13.1 at 108mph im running micky street slicks 235/60r15 if I can increase horsepower and get a better 60' that would be even better. I've always wanted to get better heads and increase some power. And lower the weight on front end too


I don't want to sound like a prick but the last thing you needs is heads. You're running at least 108 MPH and that should be a low, low 12. I'm betting with some engine tuning and more money spent on your clutch tune up and chassis you could easily see another 2-3 MPH. That puts you into the 11's.
