XE274 cam 340. Do I need to machine the heads? - 06/19/08 10:02 PM
I have a 340,rebuilt to 71 specs. Looking to upgrade to an XE274 cam kit. The website says the heads will need machining to make it work. I called Comp and I could not get a straight answer out of the guy on if i really needed to do this. Once and for all, what will it take to make this cam work in my motor?
Thanks
