Hi all
Currently building new engine, What head gasket are people using?. Boost up to 18 psi and will be using ARP head studs. My parts guy says cometic don't make one!!

I use a ridgecrest 2mm copper head gasket with an "O" ringed block. I ran 18lb for a couple of years ,and never had an issue.

Having said that...when the engine was first fired up, it leaked water everywhere. I stopped the leaks with a radiator stop leak. The guy that built the engine had not used a copper head gasket before and did not seal it sufficiently.
About 12 month later I took the engine back to him , and he sealed it properly, and I have never had another issue. That was 10 years ago.

Stay away from copper head gasket, they leak. Monotorque head gasket o ring cylinder head.

SCE do a pro copper gasket for the g54b im sure they could modify it to be like they're ICS Titan gaskets

I have used the ICS copper gaskets on other engines in the past and theres no need to O ring the block and they don't leak

Where can we find a ICS Copper gasket ?? Not keen on O ring the block or using solid copper gasket unless no other choice. The bottom end is now assembled

OK I got in contact with SCE and asked if they can do an ICS Titan head gasket for the Astron and they replied with a YES and that they actually stock them and gave me a list of part numbers

Awsome work you have done. I'm guessing by several part numbers there are varying thicknesses. Just now need to cc the head and choose the right one. I'll call Aaron Monday and have a chat.

Much appreciated Cheers

If you go to the SCE site and click on their master catalogue you'll find them on page 58 with all the available thicknesses

i used a $25 cheapo headgasket with my turbo build, was running 18psi and making over 200 rwke for about 20,000km and showed no signs of damage when pulled down.
the pistons however were in several pieces.

Im about to do the same thing and go turbo on a 4g54 however im also going injected (if that makes any difference)
With the titan gasket from summit, are there any block/head preparation required to fit or am i fine just fitting it straight on the rebuilt motor i have? (will be using studs as well)

SCE say there is no special prep to fit the ICS gaskets

Sweet. I picked up a cheap complete gasket kit with a graphite head gasket for now so if/when i blow that i know im good with the copper. (although by then its probably time to o-ring the bugger)
