Thank you for the feedback. I have a super sniper EFI system that will be going on this motor, so I should be able to monitor the tune and adjust timing as needed from the car. I was actually told that the S/R heads run a bit cooler than others out there and that is why the compression was bumped up a little. I would have had it more in the 10.5 range, but was told I should be good for pump gas with these heads and the 11.18:1 compression ratio.
