can i swap 4age head w/ 4agze head

pissonlotus · 01-09-2008, 06:30 AM

just wondering if 4agze head will fit on 4age motor and usable w/o adjustment..?
maybe 4agze intakemanifold is different since it has SC..?
i m not trying to SC my 4age, i m still gonna use all the 4age NA intake etc if that fits...

thank you

The heads are exactly the same. The intake and exhaust ports are the same. There is no gain between the two. Also, the SC intake manifold actually has been known to cause lean issues on certain cylinders, and does not have provisions for a throttle body. The throttle body on an SC is before the SC itself.
