I've had it at, and slightly over, operating temp ... parked and watched under car for several minutes both with car on, and right after shut off, so I am fairly certain there are no leaks (even heater hoses will drip onto the plastic undercover and out), and I have a compression tester arriving sometime in the next week, so a pressure test will be my next test, the if that all checks out, Ill rip the radiator cap off the N/A and test that... but if I still can't find the problem, Ill be pulling the head off...
While It's off I will also be looking at doing some work to it (cams, springs, possibly a port n polish depending if I can find someone to do it cheap enough). Was looking at some Brian Crower cams, but was also advised to look at Camtech's gear, from what I have read of the receipts the engine has full forged internals (will confirm if / when the head comes off), the better it looks ... the more work I may do before reassembly.
