I just got a 'one-layer' Spoon gasket. It's black and has two layers of material. Does that sound right or is it truely a two layer?

 

out of all the 'technical' people in here, SOMEBODY'S got to have some sort of clue, right?

 

2 ply?

 

I thought those were discontinued! They probably sent you the two layer one since they discontinued it. Check with the place you got them.

 

It sounds like you got taken for a two layer head gasket. Damn, sorry about that.

 

baah, doesnt matter which one it really is. I'm not too concerned. I just wanted to find out which one it truely was so I could figure out what compression I would be running. I can always mill the head a bit to bump the compression up a touch to make up for the difference. Just didnt want to touch anything until I knew which one i got.

 

Quoted from inlinefour.com...

"The Spoon 1ply head gasket is measured at .40mm while the Spoon 2ply is measured at .45mm. Depending on your engines configuration, you can expect to raise compression levels by 0.4. This piece is not actually a 1 piece headgasket, it is only classified this way, because it's a 2 piece that is thinner than the actual Spoon 2ply head gasket."

Just measure your headgasket and find out for sure

 

If you can measure .05 mm... my hat goes off to you. What is he going to do, hold it up to a ruler?

 

Use a caliper or micrometer...if he has access to one or the other.

 

I found some pics...

Spoon .40mm headgasket


Spoon .45mm headgasket


I'm pretty sure he got the right one

sweet, glock, i most certainly appreciate that. you're the first person to get me all that info in about two days. In fact, you're the ONLY person.

 

No problem bro, I've been thinking about getting the .40mm gasket myself. Do you think its a safe/reliable way to raise compression?

 

i'm about to find out.

the way i see it, if it turns out i want to lower compression for forced induction, i can always go back to a stock or thicker gasket.

 

using the spoon headgasket is fine if you dont mill the head, it like the mugen head gasket raises the compression safely, its fine for street use. make sure you get the low temp. thermostat and 1.3kg/cm² radiator cap also if you like to "race" the motor. Mugen or Spoon has both items. if you have problems finding it email me.
