will this cam be too big? i dont want to have to flycut the pistons. i have npi heads so i was told i shouldnt have to degree or anything but i want to ask you guys first. oh, and is this cam decent for a blower setup? i have a lead to get a set of these for cheap but i need to know that they will work on my car without any major problems and be worth the time. i already know i have to do springs, so that is not an issue really. thanks guys.
