Well I got the bad Speedmaster taste out of my mouth

John, can you post a pic of your chamber work please? Maybe a before/after kind of thing.

Yes I can but I’ll tell you on a Speedmaster head that has been properly prepped from them it’s minimal. I’ll post them up today. The biggest issue is the sunken spark plug hole and that is up to the customer whether I address that or not.
