I have one also and others here on the forum have them as well. Mine is well machined installed easy with no leaks afterwards. It took near six weeks for the unit to arrive at my door so be patient if you choose to deal with him. Sorry used mine on an old MK1 .25 80fpe with NSA 36.2 slugs, mild power upgrades and tune.

I've had one since last october, great product. With porting, a hammer weight and 6.5mm valve seat 133fpe was my high. Your results will vary.
