390 Headgasket thickness
I'd go with the fel pro, I think they compress to .040. I ran them on my 390
back in the day whern they first started putting the o,ring of a sort in them.
In the mid 70's my 390 ran 12:71 @ 105 in...
I wonder if air could be trapped in there, maybe more run time would purge it out.
