Needing some help

Replaced heads about 30,000 miles ago. Building pressure in cooling system now. I have right side down everything looked ok visibly. Took head to local shop no cracks ( I am amazed) asked him to pressure test anyway. So what to do now? Pull it and go through it check for block crack? Or clean it up good and reinstall hoping it was a gasket... Suggestions.... please.
I am planning on a turbo upgrade 35 or 40 I am running a 8 now. near future upgrade will include a program and WTA intercooler also. Thanks

Assuming this is a 6.5 I'd be inspecting the no 8 cylinder for cracks.

Minor detail.... Yes 6.5

If you would have pulled the thermostat housing first and started it you could have watched for bubbles and known which side was causing issues

Will these be visible? or need mag p. or die p?

Great idea, kinda late for that too though.

Usually the cracks are visible. Usually run verically

Visual inspection shows nothing other than a nice cross-hatch pattern. Guess I will clean it up. chase and clean the threads good and put her back together and say a prayer. Thank you for your responses (BTW your neck of the woods is on the bucket list for the Burb!)
