    Superjet westcoast head help!!!!!!

    I was using the ADA Chart, with 30cc domes. Pineapple is right, if you are using a stock gasket that is going to add CC'a and a lot of volume. That would lower compression considerably. I am more familiar with the Westcoast Kawi head which uses a special very thin gasket. I am unsure on the...

    Superjet westcoast head help!!!!!!

    OK, then those are 30cc domes. I cannot remember the Yamaha Part numbers, and would recommend measuring the chamber Diam. 701cc should be about 82mm. If they are 701 domes, compression is going to be in the 220lb range.... Race gas for sure...

    Superjet westcoast head help!!!!!!

    The domes should have a number on them, near where the plug mounts. You may need to remove them to see the number. Number would be the size of the domes in CC's. Some of the early heads/domes did not have numbers, and in that case the only real way to tell is by CCing them.

    Sorry, I just realized, you want a Blaster set up.... I do not have any blaster drive shafts, you will have to find a used one. I can still build it for you if you send me the B1 drive shaft.

    Want to Buy 148 Mag Pump - Blaster or SJ

    They are not near as bad as the early 144's were, BUT they are not perfect out of the box. (144's are still out as well). Press is still too tight, and the bore is not straight.

    Superjet help

    Cylinder heads available here, girdle, and standard. IMO go with a girdle head. Cyls can and will crack with any aftermarket pipe. NOT just the dry pipe. Installation is easy. I have more colors available than shown on my site. https://www.watcon.com/engine/cylinder-heads
