Dart Aluminum Pro 1 Chevy Cylinder Heads, 64cc, Angle Plugs
                        

Dart's highly popular small-block Pro1 heads are loaded with features, which is why they are among the best 23° aluminum heads on the market. Highly efficient chambers feature excellent fuel distribution while the five-angle intake seats shear the liquid fuel and air as it enters the chamber. Spark plugs are located high and and as close to the center of the chamber as possible for a complete burn.

The 180cc and 75cc ports feed 2.02" intake and 1.60" exhaust valves using 1.25" diameter springs that can handle up to .520" lift. For gaskets use Felpro 1205 (Speedway 344-1205) on the intake and 1404 (Speedway 344-1404) on the exhaust. A good starting point for plugs is a AR3934 Autolite (at right).

  • Flows a streetable 257 cfm intake/172 cfm exhaust @ .500" lift
  • Best suited for engines making 400-500 horsepower
  • Cast from 355T6 aluminum alloy
  • Stainless Steel valves
  • Five-angle hardened valve seats 
  • Accepts standard intake and exhaust manifolds or headers
  • 1.25" Comp Single Valve Springs w/ 7° steel retainers (.520" max lift)
  • Includes rocker studs & guide plates
  • Ready to install

Fel-Pro P1010 S/B Chevy 265-400 Copper Ring Head Gasket 4.166 In. Bore
                        

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.
