sell you a whole E motor for 100 if i still have it i will have to go check
it can be done but the only reason is the reason he is doing it for. 89 KAs had the highest compression of them all at 9.2:1 with the DE head it will push the compression ratio to 11:1i'm pretty positive you cannot run a dual cam head on a single cam block. there is a lot of differences in the 2 designs. you CAN run single cam pistons in a dual cam for higher compression.
