    I'd rather not spend 100 bucks on a headgasket with +.020 over bore. Does anyone know where I can get one for cheaper than that? its for a D16Z6 bored to 75.5mm (.020 over)

    Or

    Has anyone ever modified a regular bored one to fit? It would only be a quarter of a millimeter around the edge. I figured a dremel would work but I'm worried it would weaken the headgasket. O and my CR will be around 11:1
    Thanks guys.

    Thanks for that bit of information, I did not even know you need to buy one for .020 over. My suggestion is check eBay.ca.

    Just pay the money, no DIY head gasket job is worth doing. $100 is not bad considering you might spend $500 or more fixing your mistakes.

    IIRC, stock D-series head gaskets already have like a 75.5mm bore.

    No, 75.5mm, because people have already measured(many OE replacements are around 76mm).. :p

    If you never noticed, Honda sells OS pistons up to .5mm, but they do not sell "OS Headgaskets".

    I actually have an old gasket laying around somewhere(just the metal part though), but the caliper I have is not accurate(plastic one....my other one broke when I left it on top of my brother's car and he drove off).

    The info may be on Onecamonly.com...may be in one of the stickied threads. If not, you can always ask. Plenty of guys with calipers on there.

    Did you get it measured? That would be SWEET if it was 75.5! Save me a good $45 :)
