Heya, I'm assembling an av7 motor with a biturbo kit (50cc not much faster than stock if not the same) and a phbg intake. The intake is larger (I don't want to say much larger, but it is significantly larger) than the intake on the cylinder. How should I match these? should I draft the intake port into the size it is at the inner cylinder wall? (if that makes sense..I'm having a hard time using just words to explain it)
Also, how do you guys like to run your stock/almost stock kits, in terms of head gaskets?
