Personally I'd go with the 049s
If you are sure of your compression ratios you will get more usable torque and better flow with the 049s with big valves and the same money spent on headwork. If you want more than 9 to 1 then mill the heads, angle cut, yada.Originally posted by jedi 1
this is why i used the small dome piston instead of a flattop with the 702s which would have given about 9.0:1 but after the head swap to the open chamber head would have only been in the 8:1 range.with the 2399 piston and 049s ill get 9:1 and better.i think ive got about 10:1 right now with the 702s
Just an opinion, but if you want more street power you may be happier with the open heads.
Sounds like you are on the right track for you. Good luck and safe, fun driving.Last edited by jobberone; 07-20-2004 at 10:03 AM.
