OK so here is the dilemma. . im using an h23a(vtec) block and an h23(non vtec)head. . what are the differences in the head gaskets? Reason being:
car is ran in circle track class we call " mini-stock" and we are not allowed to run vtec. my stock non vtec h23 block had a hole in the side bought a whole h23 vtec engine with good bottom end. put non vtec head on piston hits bottom of head due to head being shaved i assume. but cometic offers a .80 headgasket which will work perfect for my application but it is for an h22 head. . will it work or are the passages/ports/ in wrong locations?

im h--series illiterate and have no idea. d/b series no issues but this is foreign to me. . any help is greatly appreciated!

You should use the gasket for the block you have. Im not aware of a difference between heads from open or closed deck engines. So if you switched to a open deck block, then Id assume you should buy a open deck gasket, for a H22A4.

I know its bad to run a closed deck gasket on a open deck block. But it makes no difference to run a open deck on a closed deck block. Go get a thicker H22A4 HG and you will be good.

Ive never heard of someone putting a non-vtec head on, and take the vtec head off lol. But if you can swap one way, im sure its the same thing just reverse process.

Yea, thats the rules for that class and the only other h23 block i could find was the vtec one in a pinch,it ran great but we had contact from the piston to the cylinder head in number one, i just dont feel like spending $140 to find out a gasket wont work. the h23 non vtec head gasket is what i used last time and its jus not thick enough as stated.
and i cant find a thinker head gasket for the h23 only h22.

Factory/oem is .030", this is a .080" thick one. Almost 3x's that.

thats what im trying to buy, but wasnt sure if it would cause issues with a non-vtec h23 head. on vtec h23 block. lol wasnt sure about compatibility between h22-h23 head gaskets.

Why not lock vtec in the h23a vtec head? Technically you wouldn't be running vtec.
