Now to know what size injector's I need(I was just thinking 42's...not to big and the duty cycle can be turned down), and to order my fuel pump, also find some pushrod's. I'm looking at the TR set, and also at the Comp Cam Chrome Moly's.

I'm super stoked Very Happy

Do you really need injectors and pump with just the cam? Might save you some money.

Congrats! your gunna love it. i went with a 230/230 .600/.600, its amazing. AS FAR AS INJECTORS I WENT WITH THE 36LB'S, mine runs great. i had some idle issues at first but that was the tune. are you gunna do the work yourself?

It's gonna get some spray down the road, and maybe heads in a year or so. Besides you can always go to big and have them turned out, you can't go to little and have them turned up.
