Well, the intake valve is canted, the exhaust is at 0 degrees.

I looked at the facebook pictures, the piston sitting at zero deck is the Sealed Power P814CP which has a compression height of 1.755". In a 9.600" block with a 6.123" rod, the piston should be 0.067 down in the hole. And in the late LA 9.577" block, it should be 0.044" down. So how did they get it to zero deck? Either stroked the crank or a 6.2" rod.???

BTW, I love those $1000+ rocker arms, I'm going to buy a set right after I buy their $700 intake manifold. But wait, the Enginemasters entry didn't use it.

Years ago I was posting about Poly head flow and Brian at IMM replied that he had worked on some much earlier, lost the flow sheets, but he remembered that the best results came from moving the intake port up as far as it would go. But to go from 210cfm to 330 is beyond my wildest expectations.

I hope those guys haven't quit their day jobs. As much as I love the Poly motor it isn't worth all the hype they're trying to stir up.
