Default Re: Snyder’s 6:1 head

Very often cast iron warps as it ages. I have 2 cars with MT CAR cast iron brake drums and they always need to be skimmed when new.

I have a 5.5 Snyder head that I have used for 25,000mi and no problems. I had it checked before I put it on and it needed skimmed. I also check heads any time I remove them.

Welcome each day
