The horse is dead

Ive never had to grind a **** ton of metal to make a gearset fit. Pointless comparison.

Unreal. Are you this obtuse in the real world?

You are using stock heads. What are your stem heights?

If you don’t know that you don’t have a clue.

If grinding on a cylinder head, of which we know nothing about makes you that pissed off its time for you to take up checkers.

Let me know what the stem height is, or a close guesstimate. That may explain why they didn’t just bolt right on.
