    Is anyone running these heads and what performance gains over D0OE 351w?

    Gaskets?

    Upon looking for O-Ring gaskets for these heads the only ones I can find are Felpro 1006! Does anyone know of any other manufacturers making these?

    Im running windsor jr lites. Their good heads i havent had any problem with them at all and i did use my car as a daily driver for awhile. I did some bowl blending and minor port work before installing them on my 11-1 347. MY car at 3000lbs will go 7.19( eighth mile ) on a regular basis at the local bracket races on 93 octane.

    check the above website. compare the windsor junior to the stock GT40P. They really don't have a good stock D00E comparison but it is not all that great. Notice the P head outflows the junior on the intake side but not on the exhaust side.

    7.19 ET is impressive on the street, was that with slicks or a street tire?
    My set of heads have been O-Ringed!

    Did they give proper torque specs? If you mill the ring off the heads what cc will the chamber be? A nice bump in compression!

    I don't need the o-ring , they came this way and can be milled off because I have no power adder! All good info though...what is your engine combo?

    Are you positive the flows measured for that head are correct on that site? I've read that world windsor juniors can flow over 200cfm on the intake out of the box.
