So I have, what i believe is, a NOS head gasket i am almost ready to install and wondered if any sealabt should be used for install. Every thread i can find only talks about the new steel or copper gaskets. Are they better? Should i buy one of those instead? I would think original should work just fine. Heres a few pics

Also, should steel enforcement between cylinders 1-2 and 3-4 have solid steel to the block or to the head? You can see a picture in above post where steel does not connect and the other side it does.

All my questions are answered in TM9-1804A on page 94-95. No mention of sealant so I will install dry. Hoping this gasket will last a long time.

Good assumption. Unless the gasket directions specify the use of a sealant then don't use a sealant.

Never seen one like yours. I hate the steel , one sided felpros. The fiber ones have worked fine for me, but they had a complete metal surround on the inner cylinder areas. I've also had good luck with the new copper gaskets. If they blow/leak, it's usually between cylinders. Next one I install will be copper. Just my opinion. John

This SB is for the F134 but there's enough similarity it may help:

The TM states to install with logo facing up which would have crimped side of steel facing up. But your posted service bulletin states crimped side facing down. I looked up Detroit gasket and mfg company but found nothing. Since i have no manufacturers instructions, i will install as per the service bulletin. If it wasnt for that, i would have installed crimped side up.
Fingers crossed. I plan on painting before reassembly so may make another trip out to Brian Asbury as i know he has a few different head gaskets on hand.

I see it said to retorque after the engine reached operating temperature. There has been much discussion on letting it cool down after reaching this temp before retorqueing. I find this comforting because I retorque while it's hot. I do it again after driving it a week or so. While it's hot! Works well for me. John

Thanks for that first hand experience. I will do the same.

Did you note the date of the SB? Did you note that it applies to the F-134?

I noticed your head gasket was part of Engine overhaul gasket set A-1537 which is for the WWII jeeps. This set included Head Gasket WO# A-8558.

The gasket set for the M38 is WO# 648054, ORD# 7372555 or FSN 2805-737-2555. The head gasket in this set is WO# 638540

I have seen a factory letter warning about early vs late head gaskets for the L-134. Can't seem to locate a copy now.

Following up with what Wes has said--there are different Head Gasket part numbers for the MB-GPW and Early CJ2A engines or Smooth Head and later Ribbed Heads. Attached are the part numbers I have on early vs late head gaskets. Looks to me, you need to source a late L-Head head gasket.

All the neat columns that tells what fits what does not show up here. If Wes can post a chart, I can send him a clipping of the file in Excel format.

Part Group Part Type Part Description MB 2A 3A 35 3B J5 38 A1 Manufacture Part Number Remarks About The Part

MB-GPW Early CJ2A Fel-Pro 7267 B For the Smooth Cylinder Head
Late CJ2A--CJ3A--M38 Fel-Pro 7285 B Ribbed Cylinder Head--Recommended for Heavy Cylinder Over-Bores .060--.080 etc.
MB-GPW--Early CJ2A McCord 6080 For the Smooth Cylinder---Medal on Both Sides
Late CJ2A--CJ3A--M38 Victor 1023 K Has Water Jacket Slots on Right Side of Engine

Harold,
My email addy is at the bottom of my posts. Just email the file to me and I'll get it up on our downloads page.

Thanks Harold and Wes. I am going to try and source out another gasket. I would feel more confident with a gasket that has a full metal surround around the cylinder.
