    806 head ?

    ok guys dont beat me down here lol

    im buying a set of worked over 806 heads off a friend for a cheap price. he put down 430ish at the wheels through a 9" in his camaro with these heads. anyway, im wanting to get them milled alittle bit to raise compression and help my bigger cam.

    from all my searching i couldnt find anything regarding the 806 heads and compression ratios or chamber cc's. could anyone tell me what the stock cc's are for these heads and how much metal needs to be shaved off inorder to make around 62cc's?

    i figured if im taking off my 241s and just get them milled, i might aswell put on a set of ported 806s and make a weekend of the swap without a down car for a while

    my trans am is already cammed with bolt ons, ls6 intake.

    Didnt they come on the earlier LS1s?

    If I remember correctly they are perimiter bold heads. Probably will need different vavle covers and I even think your coil packs MIGHT bolt up differently. Dont quote me though.

    Also, they are pretty much the same I think in terms of flow and compression as the 241s though the 241s are MARGINALLY better. But if they are ported and polished they are probably a little better.

    Check the valve cover thing though.

    those '98 style valve covers are a bitch to work around man 'cos you can't just take the coil packs off and access the cover bolts easily (for the back where it's hard to do anything)...
