I read about a person having some problem with mounting an intake manifold to these heads. I understand the intake runners are raised. Can you recommend a good low profile intake manifold and gasket combination?

These are standard 23 degree heads. They are not raised runner. Any stock SBC intake should work with these heads. Part #3252101 is a popular choice with gasket #3441205

These have a reinforced deck area and are quite substantial. We have had amazing success with them. We have had no reports of cooling deficiencies of any kind.

Designed for 1955-86 262-400 c.i.d. Chevrolet V8s, the award-winning RPM Air-Gap incorporates the same race-winning technology that's used on the Victor Series competition intakes. The air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power.

Manifold features rear water outlets, two distributor clamp locations and nitrous bosses. Accepts all 1976 and later alternator and A/C brackets for the street. The heater outlet boss is angled for proper fit over the valve cover. The temp sensor boss clears all waternecks.

  • For square-bore carburetors only
  • No provision for exhaust-heated chokes and no exhaust crossover
  • Not for 1987 and later cast iron heads
  • Will not fit under stock Corvette hood

Fel-Pro Gaskets 1206 S/B Chevy Intake Manifold Gaskets, 1.34x2.21 Inch

                        Fel-Pro Blue Stripe premium quality intake manifold gaskets for Small Block Chevy (SBC).

Fel-Pro P1010 S/B Chevy 265-400 Copper Ring Head Gasket 4.166 In. Bore
(Part #3441010)
                        

These Fel-Pro gaskets work with both cast iron and aluminum heads. Pre-flattened steel wire ring gaskets have the strength of steel wire sealing with minimum brinelling of aluminum heads. Pre-flattened copper wire ring gaskets will not brinell aluminum heads. They offer superior heat dissipation. Multi-layer steel gaskets offer current leading-edge technology and provide a long-term, leakproof seal called Perma Torque MLS.

  • Gaskets are sold each
  • Pre-flattened copper wire
  • Nominal compression thickness: .039"
  • Compressed volume: 8.9 cc
  • Recommended for 86-91 Corvette aluminum heads. Max 4.155" bore.
  • 4.166" bore gaskets can be used on 400 race engines with up to 4.155" max bore with minimal chamfer.
  • When using aluminum heads, we recommend gaskets with soft copper wire rings (such as 344-1010). This ensures that the aluminum head is not "scarred" by the combustion seal. Shim style 344-1094 will also work well with aluminum heads.
