Head gasket bore specs??? I have some Felpro head gaskets that are marked 4.135 bore that came with my 5.3 heads.
Are they suitable for a stock bore application or not?
I can't compare them with the originals yet as I haven't started the swap.
Thanks, Tom.

I just did a head swap and used Cometic .040" x 3.910" gaskets. Your's sound like they are for a big bore motor. I would be concerned about the seal points around the sleeves.

That's what I thought 
.
I don't really know why 4.135 bore gaskets would come with 5.3 heads.
Just wondered whether I was missing something.
And as I'm in the UK it's not a simple exchange matter!!!!
