    Head Gaskets to change compression?

    I know there are many gaskets availible to lower compression to make engines more boost-friendly. After reading a few posts about raising compression with new pistons to gain a few HP, I wondered if a gasket could be used to do this (less of a gain, I'm sure, but also cheaper). I've searched for high-compression gaskets online, and I coudln't find any. Do any exist, or is this just a bad idea?
    My engine has fairly high compression already, so I don't think I have much to gain from this. Still, I'm curious!

    Also, could greater compression as a result of a head gasket be dangerous with stock internals?

    Not really, the stock gaskets are the steel type, which are very thin as it is.

      not really cause it doesnt raise that high i think its thinner to raise thicker to lower it its probably the psaceing by space further away lowers it a bit closer which is thinner raises it cause the head is moveing closer to the piston. Im not sure but i think that could be it. but no it wont . Theres alot of higher compressin headgaskets like cometic and spoon and mugen .

        You are correct sir. compression is taken calculated as the pressure of the air when the piston is at TDC(top dead center) so the higher the piston is in the cylinder and head assembly the higher the compression. A ploblem with that maybe less life in the gasket. I haven't been able to find lower compression head gaskets so Deevergote could u direct me to the site u were on?

          I'm not sure if I've come across them on websites, or just read about them in books. If there aren't manufacturers that produce them, I'm sure there are companies that would do a one-off job. I just did a search, and I couldn't find anything. F22 or H22?

            What about milling the head? Is that an option with the stock gasket? I've been thinking about doing that with a VTEC head since I got the car.

              Yeah but you can mill the head just beware that theres a couple of factors to take into consideration. When you mill you cant turbo itat all i think from what i was told. And expect it to run right good luck cause the auto tensioner will fail and fuck up the engine to counteract that our h22's have to use a h23 tensioner this is from what i heard from fizzbob.

                Whoa, punctuation...anyway I wanna go all-motor if I do decide to mess around with the F, although turboing is probably the easiest route (non-intercooled kit for $1650, hmmm...). I was planning to get an F20A for the bottom, and mill either an F22B DOHC head or an F22B1 SOHC VTEC for the top, mill the top to about 10.8:1, PnP, and maybe get new springs and valves. However, being that that's a pretty labor intensive job it would probably be best to just get an H22 or turbo the F.

                  From what I've learned & read:

                  Milling can work to raise compression, however there are some issues to consider & you can't go too much.

                  1) piston-to-valve clearance
                  2) timing belt may not be able to fully tighten up slack caused by milling
                  3) may need to use a different gasket to properly seal, depending on how much you take off

                  I've have heard it work successfully though, you just have to pay attention to the relevant issues you create in doing it.
