would it be possible to throw a 24v head on my 94 cummins block instead of a 12v head

 

you need the 24v pistons too and some other things if im not mistaken dont know what all you need for certain but i do know you need the pistons

 

Yes you can do it, several guys have done it or are in the process of doing it. 97 CTD on CompD is doing it to his this winter, might shoot him a PM and ask what all he had to change.

 

oh thats ok i swaped my stock head for a head already milled base, o-ring, port and polished and intake and exhaust springs, i just figured that since my brother has his head off i might swap them but i want to get the truck going now
