Stock head gaskets, -.010"milled 243s @ 63cc, and 371CID should be about
11 to one compression...maybe a tad more but the 233/239 cam should run
well with this combo on 93 octane.

you might be close but i think you will be good, not positive though. best thing to do would be to measure. Im sure there are more than a few people on here that are running the same setup as you and have checked their PTV. Hopefully they will chime in.
