The Stovebolt Site Forums The Shop Area Engine Shop Phantom 235 Head, 3835913?

Hey Tim,
I can't answer you question about the 848 head, I will look in my Service news, but as far as the 53 235, the block, crank, and pistons(cast iron on splash, aluminum on full pressure) are different. The splash engine also used solid lifters and the pressure engine used hydraulic. The splash engine was also used in the big trucks, most likely because of the torque from the heavy pistons.
The main difference between a 53 head and a 54-55 head is that the 53 head is not drilled for the four bolt valve cover.
I use up my 53 heads on 53-62 engines where the customer wants to use a 216 valve cover.
