whats the most flow and hp you have seen from a sbc pro1 230 heads and who did the work? i have a set that top out at 317 at .700 lift ,but im looking for more instead of going to 18 degree heads
Without putting a 2.125 or even a 2.10 valve in the head, your done. Most likely it has a 2.080. Rons is very good with these as I also. You can race a dyno if you know what your doing. Any power gain you get with a dyno over what you had will add to the e.t. unless your stupid and don't use the combination correctly. I have seen more power run slower, but as I said, they were pretty stupid.
