For what it's worth, 86mm bore with stock stroke puts you at almost exactly 790cc's, I thought that was the max overbore with the aftermarket overbore sleeves/pistons available back in the day?

I have one of those 785 heads too, I played around with calculating different bore and stroke combinations and it's not real clear to me what gets you there. 82x74 is 782, 81x76 is 783ish...I dunno.

785cc's was max displacement for racing for a while wasn't it?
