I’d say the head studs can handle way more then you’re now, but its the stock heads that trend to worp a bit, causing leaks.
Even stock engines saw this problem. Especially buses..
Anyways, never torque the head studs more then stock in an attempt to make it seal “better”. It gets worse with more torque on the head studs then stock torque settings.
Thought I’d mention that again, for others that might be tempted 😉

Thanks for the heads up (pun intended &#128514
What tricks have you used to keep the heads sealed in the past, I understand your heads are far from stock now!

When I dropped a valve seat last time (18psi) we saw no evidence of the heads leaking which is good 👍

Unfortunately none that can be used on cast iron liners.
Even then, I promised it was their intellectual ownership or s/th...

What helps are new heads (AMC seem a slightly better alloy) and keeping the bore stock, so preferably no machining that weakens the head. Good cooling and a really good tune are also just as important (and often overlooked/mistaken).
None of this is cheap though, I realize. But turbo is hp and there just is no cheap hp.
