I just got my heads back and want to get the right gaskets for them. It is a N/A Gen VI 540. The gaskets that were on there before had round water passages and had trapped some garbage in the heads. I'm planning on using a sea strainer, but I'm wanting gaskets that have the bigger water passages (triangular vs. round).

*edit*
Part numbers would be a great help

Fel-Pro blue teflon head gasket is 17048.

that looks like what came off of it. would it be alright to trim near the water passages?

In my opinion, Cometic gaskets are the way to go.

Du,
I am not certain exactly where you want to trim the gaskets, but gaskets are designed to restrict water flow in certain areas and allow it in others. By messing with the design, you could cause hot spots in the cylinder head, or the block due to improper water flow. I would leave the gasket the way it was designed and try to keep the water clean.

if I'm not mistaken, those gaskets are made to be used on Mk4 (small round holes) and Gen 5/6 blocks (larger triangular holes)

but you're probably right. any one have a number for the cometic gaskets?

BillK glad to see you here.
Is my motor ready?
Give me a call Donnie

Cometic in mine

Du,

Try performance gasket 262-677-4690....I think they carry Cometic.
