Hi Steve,If you are still in the planning stages of your engine can I suggest trying to locate a set of 452 casting cylinder heads, they already have hardened seats so you won't have to worry so much about losing the exhaust seat from the available fuel, it's not a pretty sight. I have ported many, many sets of 906 and 452 heads and given the choice the 452 wins hands down. This is not a slam on 906 heads, they work well, it's just that 452 are more suited for the fuel out there today.

Paul, what are you using for gas and are you having any detonation? Are yor new pistons at 0 deck height and are they flat tops? Are those 906 heads at the stock combustion chamber cc's or been milled? My build will be similar to yours with the 906 heads, but will be a 413.

It had stock 906 heads on it and had been warmed up a bit by the previous owner (cam & intake). I put in a set of KB pistons which bumped the compression to @ 10:1 and had the heads ported. The increased compression REALLY woke that motor up. So make sure that is in your plan. (note: my stock pistons were @.140" down in the hole.) Paul L.
