I have flow test numbers for I am thinking it was the 049 heead which is the same in all respects.

It is a comparrison test of the Oval Port 049 vs the high performance square port with each head having same valves and same minor port work.

I am sorry those pics came out so small. If you can't get themk to blow up bigger, email me, and I will see if I can find and send a bigger copy.

Here is a site with a bunch of flow numbers. There are nubers (stock and ported with larger valves) for 049 heads which are pretty much the exact same thing as the 781's
