Just saw summit racing now says August for my headgasket...

so there goes the summer, and all of the plans.

mine lives in the drivers door side pocket, that's about as far away as I want it....

Is it okay to keep it in the console during summer and winter temp extremes? Or even in the garage? I know laptops and computers are picky. Just curious. I need to get one too at some point.

I gotta have a specific thickness to get the quench nice and tight.
I was targeting a .040 quench.
My piston is .010 below the top of the block.
so a .030 thickness gasket.


I bought the one and only one of those that anyone had in stock!
Cometic C5489-030 Cometic MLS Head Gaskets | Summit Racing

then back ordered the other one, est ship date of 6/16. so I figured yeah that's about right!


so my alternative is a .027 thickness head gasket.
So my quench will be .037.

Googling around, it seems the Minimum recommended is .035


Cutting it close, but the gasket is in stock...

that also raises my CR even more, ugg!

And who knows, maybe the .030 gasket will show up before i'm ready to actually install the heads...

I wouldn't leave it so the lcd screen is in direct sunlight or leave it exposed to sub-zero temps, otherwise your fine.

What the hell kind of head gasket are you trying to get?!

Never mind. Finished reading all the new posts. All caught up now. Haha

Summit delivered my radiator in record time without having to pay for any sort of extra fast shipping... My radiator is hardly leaking, so I really don't know how soon I'll end up doing it, but I suppose at least I have the new parts ready and waiting now.

Have you checked mr gasket head gaskets? I use they're .040 gaskets for my 6.2. They work fine. They may have other thickness ones.

Mine doesn’t like to be cold. Screen is slow and dim until it warms up.
