That is incredibly clean for a 34 year old car! I would really enjoy seeing all those mods you have planned for it come into fruition and the results they would bear.

That way you can test the effects of increased CR alone and then adjust the cam timing if you want later.

In the Honda DOHC world it is common to mill the head. I really have never taken this into consideration! I thought the tensioner would adjust for any slack, but now that I actually think about it the distance IS changed. Whoa all these years...
For my Frankenstein engine (2000 Honda CRV Block, 1994 Integra dohc vtec head, 1999 Integra type r cams, hi comp pistons) I used adjustable cam gears to fine tune the timing. I wouldn't be surprised if someone out there makes a set for your car.
