For those of you with this set up, any ptv clearance issues? Also, send me some feedback on performance with this set up. What kind of power did you make, where's your powerband, etc...thanks in advance.

 

Which cc combustion chamber are you looking at? I would assume that PP mills the heads some to reduce the combustion chamber size. I would call Gunnar at PP and ask him how much the heads are milled. I would then call Alan at Futral and ask him what the PTV would be with that cam using those heads with those valves. You should be able to get a definitive answer that way.

I would hazard a guess and say that there would be no clearance issues with those heads with the 64cc combustion chamber. Issues may arise with the 59cc combustion chamber.

I have my PRC heads milled .010 with my Torquer 2 and they clear. I don't think it's by very much tho...I've never measured.
