I have an 1992 454 chevy four bolt tall-deck engine casting # 10114182. The guy I purchased it from said that when he purchased the engine he just purchased the short block. He then put the heads on later. When I pulled the heads off just to go through it he has used two types of heads. Can someone tell me witch head I should run on this engine? I have listed the two types below.
1) cast # 346236 ( peanut ports) open chamber
2) cast # 336781 ( open chamber)
After I find out witch head to use I will be looking for a match head.
