F23A1 to G23 conversion Project

ok so i have a 2001 Honda Accord coupe 4cyl F23a1 and my original intentions were to just build the F23, however i was looking through some forums and saw something called a G23, basically H22 Head on the F23a1 block, creating a beastly combo, i contacted a guy in my area on craigslist for a H22a1 head, he told me 50$ after i talked to him and told him i was doing a G23 motor, basically its only missing the VTEC solenoid ( which im replacing with Skunk 2 Solenoid, and its missing the cover and the cams. Not a really big deal, so im going to do the G23, does anyone know what i need exactly.

Thanks








F23a1 (current head)

Rocker arms and springs are missing. I didn't think the DOHC would fit on the SOHC block.

I don't need a G23 build guide, I need to know what else I need for this head, as well as the issue of fitting the dohc
On a sohc block I haven't been able to find that out in builds, I know you have to block some oil ports on the H22a4 head...

You don't suppose maybe one/many of the links in google would have told you that? Like maybe this one?

Do you realize that's not a G23.... You don't use a H23 head....... Believe me man, I've looked all over google, that's why I came here for advice not for someone to sit there and say "google" it.

There's more but that should get you started on sourcing parts.

All said parts are on the head...not sure what you are looking at. And yes it will fit with some modification to the block.

Because YOU say so? Obviously some do since google shows that some use the H23 head.

thanks everyone for the help, just needed a parts list to start, got a H22a JDM black valve cover from my buddy and got the cams and cam gears from an asian, soda an H23 head on an F22 block is called a G22, a G23 is a F23a1 block on a H22 head........ using the H23 head would be dumb because you could pay around the same amount for the H22 head (Where i live) and its Vtec........
