Hey Dude,

Are you talking about the head gasket shims?
I have all sizes in stock including 90.5x.050"
$70

so thats what they are called are they cheaper if you use narrower pieces and build them up to the required thickness ?where are you located

been a while but i thought these rings were obsolete on mtrs after 36 and 40hp. as there is a double seal 1 on the head and another on the shoulder of the piston sitting on a lip of the head. The surfaces must be clean and if imperfect lapped in with valve grinding goo to get a perfect seal. Also i would locktite the head nuts / bolts.

check in the tech talk section ..do a search or repost there is what i would do....

Volkommen are up here chris. You'll probably meet the guys on Sunday. Let me know if you need to grab stuff.

It does not make a difference what size you get, they are all the same price.

You can use barrel spacers to get more deck height.
Barrel spacers are cheaper.

it is not necessary to use head gaskets but they do seal better and if you are building a performance engine, it is a MUST!


If you need me to bring them along on Sunday just let me know.
