    Default What heads to use???

    Hello,

    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.

    Thanks,

    The end use of the boat and engine would dictate which would be a better heads for your application. Hence more info is required, size and weight of boat, drive, purpose, rpm range, other engine components, all these factors will help determine which head is better for your use.

    781 is the better of the two. Same head as the 049.

Aaaah yes I can see a few good looking shiny tall deck motors on the beach, with barely enough fuel to get back to the launch saying, "Holy crap how fast you think that Daytona was going man? That's like the 20th time he's gone by today?"

    I can run one 781 and the other 049 on the same engine? This is going in a 56 chevy truck.

    Good call, the casting number 10114182 does show it being a 454 gen V but not a Tall Deck, nor were any 454 as produced.

    also BTW, I've always been told there may be head gasket sealing problems when using some Mark IV heads on Gen V blocks due to the revised water jackets adjacent to the lifter valley. Apparently this was rectified on Gen VI blocks.

    Looks like somebody just slapped some heads on a short block so they could move it.
