    single piece head question

    Well I have the polaris single piece head in my pro 1200 if i put 3 3/8 water lines to pissers off of the head instead of the one main exit will that effect any tunning ????? Also my main water in I have re routed so when it first comes in it 90's straight up into my 3/4 inch ball valve then water strainer will the 90 up cause any water flow issues??? Thanks guys

    It's going to run cooler BUT you can install the restrictors and have the same temps although the idea of the pissers as well as monitoring temps is to allow the cylinders to run cooler. Why not get a temp strip, install one on each cylinder and then measure your results.
    Do a couple of plug chop/piston washes and see where you wind up.

    main reason for the pissers is the cool factor

    are there specific sizes for the restrictors to make it like stock configuration?

    Well of course, that's what I meant first. LOL
    Nothing like watching them start pissin water one at a time.

    No set restrictor size as restrictions to the water inlet, hose kinks, filters, valves etc. I'd run them all wide open and see if one just runs too cold.
    As you restrict the colder cylinder(s) it will send that extra cool water to the other warmer cylinders and aid in their cooling process.
    Most guys just run them straight out and not worry about the temps being even.

    Check with Beerdart. I think he gets them from McMaster Carr, like 10 for a $1 or $2. Real cheap and pretty nice too.

    Restrictors can be made from a 3/8 ball valve or needle valve. That way you can adjust on the fly. Temp strips can be bought at mcmaster.com

    You're not going to get anybody to answer as everybody's temperature is going to be different.
    I usually run in 70 degree water and I run out at 160-170 after fully warmed up. During the winter I'm at least 20-30 degrees cooler but I would imagine in CT during the Winter you'd be lucky to get 100 degrees??
