Gaskets & Sealants
Made from flat material and must be used with O-ringed heads or block. Recommended for use with very high compression and nitrous oxide engines. Use DC-86 Silicone and Mondello head studs or bolts for best results. A receiver groove in the cylinder head is recommended for compression ratios over 12.5:1 or 300+ hp of nitrous oxide.Specify net bore and thickness in ‘Comments’ field on the bottom of the order form. (This is a ‘Special Order’ item and cannot be returned.)
.040″ thick compressed head gaskets. Fits up to a 4.250″ bore. Excellent for marine use.
Dual face 1010 tin plated carbon steel graphite composition head gasket that will fit up to a 4.220″ net bore. The compressed thickness is .038″, 1/2″ head bolts or studs will fit fine. This gasket will work with up to 13:1 compression with an O-rung block (.041″ wire +.010″ – .012″ above the deck surface). Do not use gasket sealer. Recommended for use with Aluminum Cylinder heads and other engine applications, especially when experiencing head gasket problems.
Steel core Grafoil® facing, “Pozi-Seal” Beading, silicone coating and stainless steel fire ring head gaskets. The I.D. bore of the gasket is 4.260″ and is .051″ thick and contains 11.9 cc’s. This gasket is a must if you want to lower your compression ratio a little bit or to obtain a little more deck clearance. Recommended for use with Aluminum Cylinder heads.
Made out of a high-density 8092 material, high temperature and has very little crush. (End seals included upon request, no extra charge.)
Recommended for high performance and marine applications (end seals included upon request, no extra charge.)
These stainless steel plates easily block off the heat riser passages on your stock cylinder heads. Indentation goes down into the head, attach with a small amount of high heat tolerant silicone then place intake gasket on top. Reusable.
Although this is not a gasket, this item is commonly ordered with our intake gaskets. Fits all Olds engines, small and big block. Our valley tray is designed to keep hot oil off the bottom of the intake manifold, allowing the manifold to stay much cooler for efficient performance. Will fit all stock cast iron and aluminum manifolds (except Toronado).(Small blocks must be drilled and tapped to accept this valley tray. Will only fit small blocks with Edelbrock 7111 Intake Manifolds.) Reusable.
