I approximated the piston specs from here: http://www.d-series.org/forums/engine-b ... -info.html
got the other block info from here: http://en.wikipedia.org/wiki/Honda_D_engine#D14A4

entered everything n the Zeal calculator and:

actual compression might vary by a few points depending on the dish volume of your pistons. I couldnt find authoritative numbers for that anywhere so I guessed 5 cc. also the head gasket thickness will affect your compression numbers. I strongly recommend going to that webpage and playing with that calculator. its fun. :)

you should be able to swap heads straight away without any issues.

Couldn't find this? :mrgreen:

Stupid google not returning my site since a year or something...?
[edit: entering "piston dish d14a3" gives me as 3rd hit! And 4th hit is correct page]

So dish is -5.4 (you were really at the money!)

And Zeal forgets compression of the gasket which should be 0.028 when installed.

But you were close, I got CR 8.50
