For one, the head bolt holes might be to small.
I am 99% sure they don't fit.
X2 I'm with these guysI could see a Z6 HG fitting a SOHC ZC, but I'm almost positive it won't fit a DOHC ZC. You need to look for an HG for a 1988/89 Integra.
It's not, DOHC ZC OEM Head gasket is the 88-89 Integra (USDM). If their head gaskets leaked, then they had other problems you didn't know about.I've only seen cometic for the d16a9, and of the 3 that I know have been used, they all leaked. Even on Nasp engines.
Have you got a link ? And I think the d16a1 is different to the a9.
Did they have the block/head resurfaced to a fine level? The stock D16A1 head gaskets are graphite and conform to rougher surfaces better, while the MLS need a finer surface to seal properly. If you install correctly you shouldn't have problems, I've used them the correct way on maybe 5-10 engines without a single issue. I don't know what you guys are doing wrong :thinking:I've had the same experience with Cometics on the ZC as well as a few friends.
There's not "good" way to redrill the dowel location on the Z6 gasket so it can be used with the ZC so I would have to say no it won't work.
I've never had issues with the stock gasket even under boost.
