Hi Folks,
Hoping for some math wizards to chime in. I have a OZ250-2V head that was milled .050”. I’m using the Victor head gasket (.044” crush per the handbook). My block is unmolested, no decking or anything.
I have a set of non-adjustable rocker assembly with the stock pushrods (8.230”). Will these work, even with the head cut?
While I have two sets of adjustable rockers, I didn’t know if it’s necessary to go out and spend the money on the adjustable if it’s not needed. Note: eventually I’m switching out to Yella Terra full rollers (already on my shelf) but that will come with the bottom end rebuild in the future. That’s my avoidance with wanting to spend the extra $$ on the cup-ball pushrods for the adjustable rockers.
Here’s my math, with the understanding that the hydraulic lifters can absorb 0.125” difference:
.050” Head mill
.044” Victor gasket thickness
.025” old FoMoCo gasket
.044”-.025” = .019” gasket increase
.050”- .019” = .031” lowering, well within the .125” lifter accommodation.
Did I do this correctly?
Cheers,
Matthew
