Hey guys just got my head resurfaced on a long 460 and now my push rods are too long. Any advice? I've heard of this happening before but never experienced it personally and it's VERY time sensitive to getting it back running thanks.
HELP!!

Rather than disturb the head again, just fit spacers under the rocker towers?

I wonder if valve were recessed in cylinder head too deep causing valve stems to protyrude to far out of head which in turn would cause pushrods to be too long.

Thicker than specification head gasket will lower engine compression ratio causing engine to be more difficult to start operating.
Honestly not sure how much was taken off. But hmm. I might could make some 1/4" shims. Previously I had full range of adjustment and now the rockers are adjusted all the way out and still need more. I would think a 1/4 inch shim on each tower should be plenty. Surely they didn't remove more than that.

I know but if you take some out and you put back what they taken off with a gasket then you end up at the same point you started from.
