Misses under hard acceleration. WHY? Ideas?

[trucken]

just did head gasket and studs. After assembly turned up the tune a little. Jumped on it a bit, got a bop, bop, bop kinda miss.

Only thing I can think of is lash was a little loose (I notice while re-assembling) Figured I adjust later after running a while.


Any Ideas?

A look below will show the mods.

Valves have been adjusted, No difference in Miss. Now you got it straight.
