5.2L head gaskets FYI

[80FoxCoupe]

Many of us are running a 5.2 (3.700 bore) bottom ends. Cometic traditionally has not offered the MLX version head gasket for the 5.2, only the standard MLS. The MLX features the stopper design where the center layer is folded back onto itself. Creating additional stack up at the bore, which promotes cylinder sealing.

I simply put in a call and they accommodated! Below is the PN for .044 compressed which is fine for most setups unless your heads or block decks have been milled considerably. Ask your engine builder for your HG thickness needs. Simply call Cometic if another thickness is needed.

I have previously ran oem Predator head gaskets at 26psi or 1300whp with success. Those measure .036 fyi. Making a move to the .044 MLX as i plan for a bit more power. Also note, I have a gen2 and this gasket will not work for gen3.

I had a similar experience, where they made me a set of .075” thick Gen3 gaskets. Top notch response!

Will these not work on Gen3 due to the oil feed hole size?

Yes, they are absolutely great to work with.

I'm assuming the oil feed hole is the issue, but I'm not familiar with gen 3 honestly.

If they haven't shipped them, you should change the order!

I wouldn't worry about it, you can make plenty of power on MLS

Asked cometic about a gen3 3.7, they are a month out.

For anyone considering these, lead time right now isn't bad; ordered today, ships the 31st.

I also asked about a different compressed thickness and it looks like they only offer them in .044 as per Fox.

Took about 16 days to get
