I just finished replacing the Edelbrock alum heads on my 49 Merc. powered 32 hi-boy.I could not get the alum head to seal properly and the engine ran very hot .
I had the same problem with my 59a powered 36 and replace the alum with stock CI heads and the problems went away.The merc. engine has a Isky Max1 cam and the heads needed to have relief machined into the head and the area area above the cyl needed to be contoured due to the Egge pistons hitting the heads.I just got it together and fired it up.Sounds and runs great.I will need to install thermostats due to the engines struggles to reach 150 deg.Has any of the barners had bad experiances with finned alum heads?
