61X cylinder question

[xXx Octane xXx]

Can someone tell me what the distance from the cylinder deck to the top of the exhaust port is (either in inch or milimeter) on a stock 61X Cylinder?

Thanks in advance,

Eric.

Off the top of my head I would say 39.5mm. I can measure tonight.

I measured mine, and it's 40mm with my calipers. Kinda hard to get them right at the top of the port.
