Cool man I looked thru gorrs site and damn this dude fills you in on all kinds of shit, about how they work and shit. I will take your word for it, i'll get his porting. One more thing dude, if i wanted to go with a 4mm stroker crank, can i just buy one and have it installed and slap my cylinders on after they are done? Or is there more stuff that has to be done? If so what are they more or less, I know i can just ask the builder these things but I know you got the skills to fill me in on the shit b4 a builder tries to bullshit me into buying a bunch of stuff i dont need. Thanx bro!
