Hey people, Can i install early model heads on late model engine? I now they switched from bottom breather in1991 and switched to breathing through heads into air filter.
Thanks

 

Can you physically bolt them on...yes
It an extremely bad idea...YES!!!!
Your engine needs to breath and if you put case breather heads on a head breather motor it won't be able to.

BTW '92 was the last year of the case breathers.
