welcome aboard! cool car you got there.

They are titan gaskets, heads were studded etc, kinda surprised they went, but my rad went early in the season and the car got to 270* so it musta messed the gasket and slowly broke down or something.

I just bought my first house so I move in in november. for the time being im saving for the house so im broke! lol

is it a GT4202 your running? those numbers at 8 psi are encouraging. Im running the same tubo but on what I would consider a much more extreme setup. Just not running yet

Its a garrett TH08A64 (off a detroit desiel) It has a .96AR hot and a .95 AR cold with a 74mm turbine cold side.

Also update..

Well cylinder 8 pumped out a ton of coolant.

Pressure tested every cylinder and it was 210 across every one!

Now the back 4 rockers on both sides started to rust so I need to take them off and wheel them, Im gonna pull the heads next week and see if its the head or gasket.

So kinda good news!!!
