i need help trying to figure out what kind of heads i got the only thing that i have is the code inside that reads m6048e35. any help would be appriciated!!!

 

what engine are they on?

 

on a 302 i pulled from a junkyard. i got lucky and got a crap load of stuff in it like roller rockers, forged pistons,cam,double valve springs,oversized valves,cobra intake manifold + alot more and it is all new. i measured the heads to the factory 5.0 heads and the ports and valves are alot bigger

 

Picture might help...I don't reconize the #

 

they resemble the factory heads but dont have a freeze plug on them?

 

on the passenger side head, look to the lower front corner, on the outside of the head, near the head bolts... does it say GT, or GTP
