Frequently asked questions

Is this genuine Cometic?

Yes. As an authorised Cometic dealer we supply genuine Cometic parts, new and not replicas.

Which bore and thickness do I need?

Choose a bore slightly larger than your finished cylinder bore, and a thickness that sets your compression ratio and squish with your pistons. The titles list bore and thickness. Tell us your pistons and target and we will confirm the right gasket.

Do I need head studs with an MLS gasket?

An MLS gasket works best with even, high clamping load, so it is usually fitted with ARP head studs and a properly prepared head surface. We can supply the studs to suit.
