Big props to Dave B for setting me straight on CR vs quench.

I have a welded d16a6 head beau aka blacksi welded up for me a long time ago. I ported the head just need a valve job. I was going to try for a low 13 sec all motor d street driven but lost intrest
Decked the head to clean the chambers up and reshaped them has best has I could.

I have been looking at doing a build with them, but can't fork out the cash to buy one just to measure it.

While I talk up the quench a lot, there is always room for improvement.

Could you explain a little more about quench vs compression?

I would like to try something similar. I have a Y8 head sitting here, a good A6 block, and some LS rods. I just happen to know a few machinests too.
Saw you post on D-series.org. The timing in the lower load sections looks pretty typical to me once you subtract the 10 degrees from the map values.
