As for questions, I have quite a few
Can I go through my local machinist to get the head ported or would Russ be a safer bet regardless of shipping cost?
I am unfamiliar with cc's of pistons, quench, ect, and need to learn, but it looks like Russ's custom pistons are the best bet?
Can I go through Russ for the cam? Or can I just get a whole set with springs and everything through CompCams?
Can I use the intake off my 4.2 and mount a Holley Sniper EFI kit to it? If so does Holley's BBD kit made for the 4.2 suffice or would I need a bigger one to support a 4.6?
Would it be smart to go with upgraded valve springs, new roller/stock rockers, and pushrods while im already replacing the timing set?
And ive seen some mentions of the 89 4.2 crank having a long snout and it causing fitment problems, what is the solution to that?
I know its alot but im here to learn! Any info is appreciated!
