228cc port, 60cc chamber and the intake valve has been unshrouded some. intake as of now flows 325@.700. the cam is .712/.688 on 106lda. these are on a 408 with 11.5:1 compression. what would be the limit with this head for max. cubic inch and compression?

what are you seeing that tells you ring seal is an issue? last time I did a leak down it showed 5%. the chambers are black because it idle with a very fat carb before it threw a pushrod.
It's not the black it's oil in chambers,exhaust ports and intake ports.
Side note leak down will not tell you what ring seal is like in running engine.
But again this is not the major problem my bet is on cam/springs.

Ports are fine will support more power than you are making with them.
Chamber looks like hell/valve job is bad at best. (Hard to fix now) they used some POS radius top cut "performance" valve job.
You have poor ring seal and and unhappy valve train.
But with all that said you are still not making power it should as is.
I would say cam/springs are out in left field .
This is what a valve job should look like.
I was going to say the same thing about ring seal, been there done that,
