Yours should be great after TurboKraft does his thing. I have currently 2 motors by Jarvis, first photo motor was built in 2002 and the other one was built long before that . No scorched pistons yet. The motor in the first photo usually runs 18psi on around 100 octane and 21psi on 112 and has around 8K miles since built 19 years ago.
The second motor photo was just rebuilt and upgraded after bending a rod ( stock rods with ARP bolts ) on the break in dyno tune about 14 years ago and now has Carrillo billet rods, 8.0 compression 3.4 liter pistons & liners and EVO 2 webcams otherwise left as built by Jarvis Tech with 993 TT exhaust and his custom intake etc. Recent break in dyno is 370 WHP at 11psi so should be lots more @ 16 or so psi and race fuel.
Does your intercooler and his fab work look like the photos of this early Jarvis one?
