    Replacement heads for 1200R motor

    Is there a preferred head for a rec (150 psi - 92 octane max) boat? What is the best choice ? Cut the stock head at Group K? Pro-tec billet head? R&D individual heads?

    All of the above. The prefered method by most seems to be a milled stock head; I know thats what Rocketman uses. Can't go wrong with GroupK.

    IMHO...i really like the Pro-Tec Recreational Head. I have been using it for years with NO problems. It gives you the compression you want and keeps the stock 1-piece design. It even looks purty!

    There is one for sale in the "for sale" section for a good price.

    John, does the stock head cover go on top of that?

    $250 from Protec, I'd probably stick to the milled stock head.... however, it looks like HopatcongGPR has one for $180, if you are looking for one, you outta jump on it. Then you still have a spare stock head.

    imho, the pro tec head is the best out there. the squish band and dome are near a perfect design for the 1200. plus, it is a billet piece that retains all the oem gaskets, bolts, etc.

    the one piece design is best to keep the cylinders tied together.

    being billet allows for a lot of future modifications for strokers and huge bores.

    typically, you can run the pro tec head with a single shim and obtain near perfect squish (.038-.041) with compression in the 160-163 area...

    Too bad they never made one for 60T cylinders. I really like the protec design.

    Got a spare already. Wasn't sure how the heads all compare. The Pro-tec is a good deal, just not sure if it's the best choice.
