Nice. I was looking to get 450 fwhp any advice as far as cam and head selection? I am going with 383 on bottom end. Well I think I have cam picked out. Just need reasonably priced set of good heads. Cam I am looking at is comp cam part number 08-432-8. 08-432-8 - XTREME Energy here is a link to view specs. Kinda lost as far as bang for the buck goes as far as supporting heads.
