Big Block heads

452 casting heads, they have 20 1/4 passes and about 1500 street miles.I put new valves, springs, shims,retainers and locks. They have also had a 3 angle valve job done. The springs are comp cams 91-116 . The heads are a little black in the combustion chamber area,the pickup in the distributor started going bad and the car got rich. If you want more pictures please let me know. Price is 400 obo
I would consider trading the for a performer intake and 650-750 carb for a 383-400 engine.
