Milling the Heads How much?

i had 60 thousandths took off my 79 318 heads. i'm gonna need new pushrods tho. i don't think it helps out compression on 318's much. maybe if i'm lucky it'll help about 1/2 a point, or maybe 3/4 of a point c/r.

it definately helps, but i don't think its a "bang for the buck" mod. it was a 100 bucks to mill my heads .60, then i had to pay 75 bucks to have my holley street dominator milled so the bolt holes would line up ok. now i'm lookin at around 100 bucks for custom length push rods. +, milling more than that can really throw off the geometry of the valvetrain. i could have bought a set of kb pistons for the same amount of money and had more compression. it has stock pistons now, i'm going with kb's and the milled heads hoping for around 9.5:1.

you could mill your heads around .30 thousandths for now, your intake and pushrods should be fine. then in the future go with some kb's. is the heads ported? if not milling it .30 and a mild port job will wake it up. hope this helps...
