Hm, not to thread hijack but where can i can a 20V head? I have a 4agze with a blown head gasket so the engine has to be pulled over the winter. I'm guessing a 20V head can bolt onto a 4agze block?

The 20V head will bolt up to the 4AGZE block, but just take into consideration that the distributor is in the rear of the 20V head. To make it fit, most swaps will require you to cut into the firewall. Also remember, that your upper rad hose will be on the DRIVER SIDE rear, behind the exhaust header. You will also have to either make or get an intake manifold due to the location of the air intake tube. Hope this info helps.

you can use the pistons of the gze on the 20valve and then boost the 20v but imo just swap in a something else in the thing. I kick myself for not swapping a rotary or something more powerful in my ea before i sold it. 20valve was a waste IMO.
