Thanks Don,
I was thinking about that, & If it was the exhaust valves then it would be
backfiring through the muffler.
I noticed this happens when I set the timing to 4 ATDC. If I back it off a
little it I don't see it.
What's the chance that the timing marks are off?
Any way to compensate for that?
I had the head resurfaced and the shop replaced the valves (so they say) to
acomadate unleaded fuel.
I'll pickup a compression tester and check it out.

Exhaust valve, burnt or sticking. Do a compression test.
