Port dimensions

[87_shee]

I picked up a set of new sleeves for my worn out cylinders and they are supposed to have slightly different port design, I can tell from looking at them that they are a bit different. I was wondering if anyone knows the stock port measurements. I would just like to compare the numbers before I change them.

Thanks.

So out of all the engine builders and other pros one here , no one has any measurment for the stock ports? Some one must know.
