What Hg Should I Go With?

So, seeing as my head is off and i was told my current headgasket is starting to let go in some spots, i'm looking for a replacement

what i currently have is an unknown brand metal HG that came on the car, i measured it with a caliper and it seems to be about 1.7mm thick

I'm probably going to get the head resurfaced, so what thickness should i go with this time? 2mm?

Problem is that i dont know if it was already shaved down in japan when they fit the new HG so it's a bit risky to not go thicker.

I did however notice when i did a compression test that i got about 145psi across all cylinders which suggests that the compression was lowered.

So anyway, i was thinking about going with Tomei but i hear that there seems to be a shortage of tomei hg's on the market?

Im trying to avoid Cometic since i've heard of allot of people having leaks with them

No issues with Cometics here. I've also reused mine.

It really comes down to making sure the head is straight and finished correctly.

There's also Permaseal MLS-R of which are around the low to mid $200's.

Permaseal also do full inlet/exhaust gasket sets for the r33's.

Coventry/Motortraders sell them and are around 1.3mm thick from memory.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
