    Well heres a Vision craft .21 Tunnel I have been working on. I purchased the boat from Beau Parsons Brand new. little stuff needed to get this boat in the water and start the break in process.

    I have the following gear on the boat;

    Novarossi Keep 21 Outboard engine
    Nova Header
    SSP NR pipe W/extra Muffling
    OS Lower Unit with a Stump FAB Cavitation Plate

    need to finish;

    install Stump Fab throttle cable holder and setup
    install Stump Fab universal Oiler System
    Drill out holes on the OS steering arms and setup

    Very nice lookong boat and build...
    Hope you are not planning on running water AND that full air cooled head?

    I needed to restrict the water alot on mine to get it to build enough heat with all the fins machined right off (so pretty much a standard water cooled head).
    Cheers

    This is how we run the head on Dons Keep. I actually cut it off at the pond with a dremel and cleaned it up.

    It is what is left of this head

    I plan to also fill in the cooling cavity with JB weld and machine a 2 to 3mm deep groove with a 3mm ball nose end mill to ruduce the volume of water. Works VERY well on my old 35+ outboard :)

    It is very important to load the Novas and heat em up hot and run rich to really get them singing... hope I can get my motor to "2nd stage" on my SAW boat as it was on the weekend on my oval boat...those cooper pipes sound soooooo good when revving hard!!
