I am new at all of this and have a lot of questions so please bear with me. First of here is the list of what I wan to do and tell me what you think.

wiseco 87mm 416cc 10:1 comp
stage 2 hotcam
port + polish
450r carb
HD timing chain
secondary oil cooler
rev box
HD head studs

Here are my questions. What is a reasonable price on a P+P? Are the HD studs needed? What kind of gasket kit do i need (any certain size)? Can I run just premium pump gas with this setup? How difficult is the 450r carb mod?
