    Need a head for G52B 1981 D-50

    My father and i are in the process of rebuilding the engine in our 1981 D-50. Unfortunately, we found that the head was cracked out beyond repair...As well as every other head our local auto parts stores can come across. Autozone's website suggest they have quite a few of the correct heads from Surefire, Moore's and American Cylinder Heads, however Autozone's representatives say that they're not actually available anymore despite what the website says.

    Also, given that we live in California, smog requirements are very stringent making an engine swap, or excessive modification, or deletion of any smog equipment with the exception of the jet valves nearly impossible (to my understanding of current smog regulations).

    So, we're sunk.

    Would you guys happen to know where we could find a good condition complete head assembly or core for our truck? Would it be possible to use a 2.6 head on the 2.0 if we absolutely had to?

    We're also looking for another cylinder head breather grommet. The rubber peeled apart when trying to remove it. A local auto parts store tried to hokie something together, but we'd much rather have a proper condition one if possible.

    We're also curious if anyone had a grill that would fit it. The truck got rear ended and pushed into the car in front of it many years ago and it destroyed the grill, but we never did get a new one for it. We were curious if anyone had grill or knew of the location of one.

    Hope to hear from you guys.
    Thanks in advance,
    Don & Andy

    I know you can put a 2.0 head on a 2.6. So why not the other way around. Pennyman?
    Sorry but you will need to re upload the photos. It went into moderation and the system dropped them.
    After like 7 posts the system will stop scanning you.

    try these guys http://www.ramscyl.com/index5.htm They accept broken heads as core. I used them for my 2.0 and they were great, very helpful.

    I know people like to put 2.0 heads on 2.6's, but i'm concerned about if it'll be able to pass smog like that. Thanks for tip, 85Ram50. We'll check with them and see if they can help us out!

    These are the pictures that i uploaded. I couldn't figure out how to edit the OP:

    You can swap a 2.6 head on a 2.0 IF it is from a 79 - 81 2.6 from a truck - it will drop the compression 1/2 point. The hot trick in the early days was to use the 2.0 head on the 2.6 to raise the compression 1/2 to 1 point. You may have to get a rubber molding kit from Eastwood to remake that grommet. I have a spare 2.6 head from an 80 or 81 truck, but I haven't looked at it in a while to see if it is any good. If you go for the non jet valve heads, you will have to get a newer intake manifold, as the bolt pattern is totally different, and it would probably fail Cali visual inspection.

    Thank you pennyman and 85Ram50. We sent our damaged head off to Rams Cylinder Heads and Ivan sounds extremely confident that he can repair it.

    In the event he can't, however, what all goes into putting a 2.6 head on the 2.0 engine? Would it just be a bolt-on, or would it require a new intake and exhaust manifold, modifying the bolt pattern, ect?

    if the head is from a 79 - 81 truck, it is a direct bolt on - all parts bolt on the same.
