I don’t see how the compression can possibly be 9.9 with those heads which are stated to be 72 CCs.
9.5 is about it, in fact that 3 angle valve job has sunk the valves enough to add another 1.5 to 2 CCs to that stock 72 CC number, now add on top of that the fact that most heads stated to be 72 CCs where really 74 CCs and you can quickly see that 9.9 is not possible! Also the lift of that Cam will not be enough to access enough flow to make anywhere near 400 hp with those small valve heads!
