rumor has it... if it is a hyd head, it is ok to use for TD or NA, and is of the same alloy.

the prechambers and valves had different materials pre '86


i think that rumour is true...  i just checked ETKA, and ME MF RA SB all have the same head :P valves and camshaft included.

this is great info because i just bought a parts car with a nice rebuilt head... ohhh yea!!!

Okay, so I gotta check the engine code... it will be stamped under the front coolant flange on the block, correct?

I know that on the back there is the displacement casting, but is there any other way to tell WHEN the head was made.... e.g. after 86?
