I would reccomend springs with any cam change... They're not that much more and well worth it...and I've heard a lot of good things bout cms cams... They have blower cams that are made for...well....blowers lol
Won't fit? Aren't they just more lift? I believe I thought about them...but if they are the ones I'm thinking of you'll def need to check ptv...and maybe even have your pistons notched... ( Some one please correct me if I'm wrong cause I'm not 100% more like 60%...memory aint too good )
