That clatter sounds like lack of piston to head clearance.

I'll look into this further tomorrow, but I don't think it's a problem. I've had the heads off previously and I recall the pistons were down the hole a bit at TDC and the gaskets were copper and seemed of substantial thickness (I must admit that I didn't specifically measure them). That said, when I pull the heads to look at the cam and cam bearing diameters this will be looked at more closely.

I appreciate all the suggestions, Tim.
