The end product needs to have ceramic seals, even if you have to make a

set

that have the corner piece like the stock seals. I don't know how that

would

wear on the cast iron. They are one piece for racing.

Lynn,
I did see the cost of ceramic seals on here a while back, then figured stock
cast iron would be good enough for my own application, but I agree they
would be the 'bees knees' for Francois's ( Mistral) application.
Also solves the problem ( as Francois sees it ) for the P-port.

I think Francois has made a valid assumption on the wear of the seals on the
P-port ( especially on larger ports) but he may be over estimating the extra
degree of wear on the port sizes and the RPM, we propose.

My opinion for what it's worth and I believe Lynn's extensive experience in
racing supports this.

Lynn what is the fit protocol for the ceramics - diamond grind the ends to
allow X end play?
