Apex Head gasket?

[TURBLUE]

Is two head gaskets thicker than the mcx head shim??????

head gsket.

I heard most people are running three gaskets.

If memory serves here, 3 gaskets is .051 ( Stock is .017) so 2 would be .034. Now I "think" the head shim is just about .052??? So, your answer is NO.

Of course, I may be wrong, tho. lol

1Crazysledder is right, you would need 3 head gaksets to make up for the shim, but I beleive the shim is still a touch thicker. If you search my posts I figured it all out last season.

I am running lc pistons and two head gaskets

shim is 60 thou that is what mine measured.

 

[TurboJamie]

There Kevin NFS2 says 60 thou thats the PL kits shim same as I had. I took it out to low for compression IMO I am running 3 stacked stock head gaskets this season 0.51" thickness.

For a trail turbo set up 3 gaskets and 12lbs is great dont heat soak the engine back to back never ending runs or deto may rear its ugly head,but on a super stage 2 14lbs is possible same deal dont heat soak the engine, the neat thing on the super charged engine with the 60 shim is throttle response is very good at idle with certain pulleys you can acheive 2-3 lbs of boost, so head shim on super 14lbs on 92 pump fuel is good for lets say maybe a run for a trail pump gas turbo. sage2b kit will go to 20lbs.

I put two on mine last year and it lasted 1,00 miles back to one and copper spray good to go now. Put HD studs in it too when it was apart.

Apex head gasket

Head spacer or shim is .0625- .063 depending on aluminum.
Head gaskets are only double in Apex and triple in RX1
Apex .020
RX1 .030
Vector .020
I also make .040 spacer for guys using 10 to 1 pistons so you can come up with what ever compression ratio you want.

Kool. Now we know the specs. Thanks......Info put into my notes......

 

[TurboJamie]

Keep in mind the shim at .625 + .17 for the gasket you are still installing = .795" over all. Alot of flat land guys will agree the compression ratio is to low.

Keep in mind a stock sled has .17" gasket so 3 gaskets would be .34" thicker then stock.

With the shim you are .625" over stock. So essentially double thie thickness of 2 stacked gaskets.

this give around 9-1....

Way too low with a turbo to get any good throttle response.

Does anyone know what mc-x sent in 04 for head gasket I thought it was single thicker gasket and would like to know for sure.
