Try an 8.5 PV.
Honestly, I think your car would respond much better with a 3310 on it, but that's more money.

Chris, I used to have a 3310 on it and I get better throttle response and 60' times with the double pumper (1.67 60' times)
So, with the 6.5 valve, do you think I'm leaning out on the top end, which is what many people suspect is happening?
The 8.5 valve, if I'm correct, will allow fuel enrichment sooner and close later....right?
Did you want my idle vacuum in Park or in gear?
