I was faced with this problem early this year.
Mine didn’t push at idle like that though, just under boost.
It was also a MLS gasket, I removed the head inspected the gasket it was “fine”.
Turns out I could fit .004 feeler gauge on the exhaust side. The car didn’t ever get hot before this either.
So the it got resurfaced and It’s good now with a new MLS.

i used new L19 arp's torqued them to 90ft/lbs
block was new head also never overheated did run only about 10 miles when i discovered temp was rising due to headgasket failure
gonna do the blocktester fluid first to be sure
and worse case re surface the head and put on new HG
so you say felpro composite will do the job??
we have ran a felpro composite to mid 30psi boost range without issue. just slapped it in and torqued the head down and ran it.
