help with heads a12

[taiparacer]

hi guys hopefully somebody can answer me this a early a12 head out of a a 1200 front mounted dizzy motor

can it run on a sunny a12 mid mounted dizzy motor and what mods need to be done to allow it to do so

or did the early heads come out in the 120y

the difference to me seems to be the oil galleries

i know u can run the later heads out of a sunny etc on a early 1200 by cross drilling the block /head
thoughts please
cheers ron

you have to cross drill the oil gallery.
There should be extensive write ups about this at datsun1200.com.
