High compression with aluminum heads and pump gas???????

.004 proud is perfect for the 1008s and My 65cc heads.I run 87E10, with a Scr of 10.7 and a Dcr of 8.6. I have run as high as 11.2/9.2sealevel,still on the 87.I have come to believe in the tight quench theory, and am running .034inch. I have run as tight as .024 on the KB107s.My TOTAL chamber volume was calculated to be 77.8cc,with the 1008 gaskets.It was measured at 78.0cc fill volume.
Your results may vary.

TripleBlack what would be the ICA on that, or the Dcr, For comparison?
