Real Steel Merlin F85 Heads

[Basil]

The chambers probably dont fit inside a 3.5 head gasket.

No apparantly the ports are too large for 3.5 and the gas speed is too low.

I'm guessing that the "F85" is some sort of homage to the Oldsmobile F85?
One thing I've seen pointed out on the Pistonheads website, the exhaust ports on the Merlins are higher than a standard Rover head, similar to Buick 300 heads, meaning standard exhaust manifolds or headers won't fit. That's not a criticism though, raising the ports is a good idea and if it produces better flow, I say good on 'em.

Still, either Real Steel are cunningly ratcheting up the tension and building excitement in the biggest advertising campaign since the Segway, or their sales department only works part-time. RS - we want lots of numbers and pretty pictures please!

I'd like to see some flow numbers. I'm curious how they compare to a set of worked Buick 300 heads.
