i am selling my fast burn heads off of my zz 383. one head has been surfaced and the cc is 59 1/2, the water jacket ended up creating a dip around number 7 cylinder. so i had a machinest add more aluminum to the head to fix the problem. the other head is at 60cc right now and would cost about 50 bucks to make it even. the reason i am selling is because i wanted higher cc heads to drop my compression on my car. Valves have approx about 6k miles on them after rebuild. asking 650.00 obo
