Hello I have a 430 with a performance intake anf shortys headers. I am in the proccess of assembling it. I was wondering how hard it is to port the heads and intake? I mainly need to knoe how far to go. I have some junk heads to practice on. I just need some instruction and what tools to have. I definately want to go with an air die grinder. I dont want to go too major!! any help/hints/tips are greatly appreciated thanks, will
