920 Head Cutaway?

[67valiant 100]

Anyone have some pictures of a cut up 920 head they could share? Better yet, a cut away comparison with an X or J-head? How big of a valve can one resonably install in these heads if not limited by bore size? 1.92s? 2.02s? I know physically the port runners are smaller, I'm just curious how the rest of the port compares.

Thanks

Charles servedio on youtube has a video of a 920 head I cut up and sent to him. Video was posted 11 months ago so it's a bit down his video list on his channel. It's titled David Vizard, Unity Motorsports, Mission Impossible 318 project 4 barrel test head cut aways!

He goes into depth on porting them and also has another video of flows of another 920 with stock valves.

And he has porting/flow content of various other mopar heads posted as well. Always a good show as he is an excellent porter with years of experience.

If you need more, I can post my personal photos and rubbings of the cut up head, but I'd have to take a deep think about it to describe them so you would understand it all. It was 11 months ago and I have been consumed with other projects.

Would love to see your pictures if you can dig them up!

Took me better part of a week to saw one cylinder up. Don't worry, that head was cracked and unrepairable.
