Ok, I searched on H-T, I used Google image, and I really can't figure it out for myself. I knew there was a thread telling the difference between the blocks, open and closed deck, all that jazz...
I'm putting a built USDM H22A4 head on a JDM H22A block.

Will the USDM H22A1 headgasket work? Is it the same as JDM H22A headgasket?

I'm basically just trying to figure out which headgasket to use, the USDM A1 or A4 headgasket. I'd just prefer to buy a Honda OEM headgasket state-side through work rather than buy online (like eBay for example).

Thanks in advance.

(Also, I posted this in the Prelude section to no avail)

what are the bare head assembly part numbers for the 95 or 96 prelude h22 and the 97-01 prelude?

 

You can use either head gasket since all bore is the same and all the oil passages are in the same places. When in doubt, I match it to the head so I know the coolant ports are the same.
