Dion,

I'm sorry I jumped all over that post. It is actually very good to see some slightly different ways of making power. You guys may hit on something good there and I was trash talking it to quickly.
It looks like your combustion chambers weren't widened out as much as mine, they look a little smaller. If that is any guide you may have compression in the 10.3+ range, but surely not over 10.5:1.
I have to say that they did a nice job on the work, I just felt with the knowledge base that has accumulated over the last year and a half, it indicates that the 2.5L valves may limit the maximum potential of the motor.
Look at it this way though, you will have one hell of a platform for the vortech supercharger! That was another reason I was going with low compression in mine.
Good Luck,
