370ci Iron Block Guys - What Head Gaskets Did You Use?
 

I had TEA send me some graphite 6L gaskets . . . Brian says they're actually 4.050 bore, the motor is a 4.030 . . .

cometic gaskets

my iron block was only a 4.000 so the gaskets i got were 4.010-4.015 over

MLS 6.0L head gaskets....... $60....... Ask Chris about them......

I've been running FelPro 4.135 bore gaskets for around a year and half now..

Kyle, I was under the impression that the MLS would not work?? I don't know why however . . .

Works fine for me.............. who told you that and why??

You know, I'm not really sure! Funny thing is I have a set of 6.0 MLS still in the package, and now I have 6.0 graphite!

Is that on a 4.0X" bore block? That seems like the gasket is way too big.

6.0L MLS are nice.

Well, I think the MLS I have may be for a 5.7 . . . can anybody confirm? Part # 12498544

Also, someone in this thread says that Corky Bell recommends to not use MLS on a higher boosted engine . . . dont' know what the definition of higher is though:

4.030" bore... When I bought 'em, the only other option was the GM MLS included in the entire friggin' 200-something dollar "kit" ... I didn't need the bolts, since I have ARP studs, so I picked up the Fel Pros ...

The graphite ones I have are also felpro's

I have heard MLS gaskets won't work with the o-rings. I have some new cometics I bought without knowing this myself. If anyone wants them they are for stock bore and .052.

Why is that? I can not see TEA selling MLS gaskets for their O-ringed heads.

That's who told me they won't work. I don't know why but that is what they told me. I have TEA 5.7 boost heads with o-rings and was told to run stock graphite gaskets. I am dissapointed as I got 145.00 gaskets I can't use.

That is surprising, because I just bought a set of TEA 6.0L stage III o-ringed heads and they sent me a set of Fel-Pro 6.0L MLS head gaskets. I told them to give me whatever is the correct gasket for the heads.

Maybe it's just cometics. I don't know, Brian Tooley is the one who told me they won't work and to use graphite. I don't know if the GM mls gaskets are any different from cometics. When he told me that I did a search on here and many people said the same thing as Brian. Someone please clear this up, to me it doesn't matter because I have both and my motor is not together but it may make a difference to others.

I see a lot of people are using Fel Pro gaskets. Does any know the compressed thickness of the 9199 gasket?

Not sure about the 9199's, but my Fel Pro 1041's are .041"

Aren't the 9199 gaskets graphite and not mls? Of course I could be wrong as I only did a search and read alittle on them. ls1290 which one did TEA send to you?
