Did some searches but still not sure due to the cam and milled heads, so here goes.
Stock bottom end
GM847 cam 234/242
Comp promag rockers 1.6 -7/16 nsa
gmpp guideplates
comp-r lifters
k-800 springs
PP stock lt1 heads
The heads were milled/resurfaced when they went to the machine shop, but I don't remember by how much. I don't know if there is a rule of thumb when resurfacing heads that relates to how much is taken off .010 maybe? If that were the case, add to that, a cam with a pretty decent amount of lift 570ish/590ish with a 1.6 rocker (I think) and I'm starting to wonder if I should go with the stock length 7.2 or go to a 7.150 pushrod. Don't know how much valvetrain geometry will be affected in relation to pushrod length?
Your input please
Thanks

Serene

why dont you check it with a length checker instead of having someone guess for you?

Yea, really the only way to accuratley guage the length of pushrod that you need is to use a push rod length checker. You REALLY don't want to mess up your valve train geometry.
