no - 5.0 and 5.8 use diffrent head bolts - but the intake and exhaust are the same - most 5.0 are 7/16 and 5.8 are 1/2 - the early 302 and 351 share the same size for a few years - the gt40 heads should bolt on - if not ( 1/2 bolts ) then you can just drill them out -

Sure... if you call 1/2" vs 7/16" the same diameter...

EDIT: Damn, too slow.

yeah i was readin about that 1/2in vs 7/16in, so ill look for gt40 heads cuz they have to be better than stock, or a 5.4l mod motor for the jeep
