Default hot engine/poor running

im running starfiret40 with sbp pipe and : GT50R RACING CARB KIT. and jackshaft, but since day one ive had nothing but troubles.

seemed to be running slow when getting hot and also blowing the head, gasket seemed fine .?

but was loosing head bolts, not like loose loose, but had to keep turning them down, i was just wondering is it getting too hot and causing the head to blow because the mixture could be wrong, because when its cold for the first 5min it runs great and then as it gets hotter it loses power, struggles real bad.

was thinking of putting standered pipe and carb back on..???

any insight to this anyone..???

ive since flattened the head and barrel new studs and nuts, not acorn nuts as was before, new gaskets top and bottom.
