Big bore gaskets

Recommended Posts

Heyy all,

 

Peeled apart the top end due to a blown head gasket (confirmed).

 

Found single layer gaskets and a gasket that looks like it's not the right one.

It partially blocks the cooling veins as seem in the pictures.

Part numbers are as follows:

Gasket: 41001-G01

Cylinder: 41001-K01

 

Looks like the part numbers match, and the the new ones I ordered are the same except triple layer.

 

QUESTIONS!!

- What's the deal here, is this the right gasket?

- If so, can I just chop the rivets to make a single layer gasket? Which layer do I use?

 

Thanks all!

41001-G01 is the Cylinder Works big bore gasket kit, you are good there.

 

Your old head gasket is correct. Nearly all head gaskets do that. The restriction is meant to help even the temperature of the cylinder bore.

 

 

You can peel the rivets and run a single layer base gasket. The inner layer is just a shim. Save the other for a spare. It's not advisable to split the head gasket. Speaking of which, pay close attention to the location of the rivets. The rearward rivet has been known to interfere with the fit. If any part of it is between the head and cylinder mating surfaces you'll need to remove it.

 

How much for the duck?

Thanks Ohio!

So I guess I'll keep the triple layer head gasket?

Much difference when the original was single layer?

I don't know. I haven't compared the 2 back to back.


Okay

Last question.
Why is it not recommended?

Cant quite find why not.
High compression, high octane gas requirement?
