If so what kind?

I'm sort of concerned about the piston-valve ratio, but I do not want to waste my time if they aren't going to work from the begining.

I'm looking into Skunk2 Stage2s/JUN3s are prolly are the most agressive I could run. Comments?

 

we've been making well over 200 hp with skunk stage 2 on ctr pistons...really good combo

 

I am running Spec B's w/ no problems, is that aggressive enough .
