SignUp Now!raised roof intake ports. How much was the roof raised 1/2 inch?.
Jay
Are you planning on eyebrowing the top of the cylinder bore to help keep the shrouding of the valve from the cylinder bore.
Also thanks for the info on the intake ports.
What heads r those, TA or Champions ? Are they for a S2 or a 109 ?
What is with the plates bolted on the intake side?
In one of the pictures you can T/A perf. cast into the head. I also see some sort of stud tapped into the heads under each intake port, what up with that?:biggrin:

Chances are they are using a multi-layer steel shim like a Cometic which requires a very flat and smooth surface. If the head surface or deck surface is not smooth the gaskets will leak. Im sure that the heads and deck are finished to the proper finish. There wont be anything overlooked on this engine. The clamp load of the fasteners holds the gaskets sandwiched in between the heads and deck. Not the surface finish of the mating surfaces.That looks really nice.
One question though...
Do you really want the deck to be that smooth? From what I have read you want a slightly rough deck surface to help keep the gaskets in place.

Without o-rings?We're not using a Cometic.. I believe we ended up deciding to use copper gaskets.
bison, there ia a self sealing copper gasket that does not require orings. It has been around for quite a while now.
Jay, it will be nice to see Nelson at more of the races now.
See ya, Kip
