pm replied to..Heads pending sale// ill let you guys know monday if they are available or not..send me e-mail address for pics.. i dont know how to post the damn things

 

will they clear the MS3 without flycutting?

 

im going to say anything with 600lift and a duration of more then 240 will need to be flycut, but im not 100%sure..fly cutting the pistons isnt a really big job. you already have the heads off so whats the problem..

 

the reason i dont really wanna flycut is because i plan on spraying the motor, and dont really want to make the pistons weaker then they already are.

 

mine are flycut and iv been spraying 100 shot for a while now

 

still have these? detailed pics? cyclepunk@gmail.com
