Small Block Chevy Assembled Aluminum Cylinder Head

210cc Intake Port, 64cc Chamber, 2.02/1.6 Stainless Valves, .650 Lift Dual Springs, Straight Plug, Pair

 

New pair of small block Chevy aluminum cylinder heads. These heads are an assembled set, ready to bolt on. Comes with features normally found in heads costing much more, including:
  • Bronze valve guides
  • Manufactured with aircraft quality high grade aluminum alloy
  • Multi-angle seat design for improved flow at low lifts
  • Advanced port design for improved flow at all lifts
  • Advanced combustion chamber design allows superb flame travel and burn
  • Additional pushrod clearance machined along outside port walls
  • Can use either perimeter bolt pattern or centerbolt valve covers
  • Threaded accessory holes in ends of heads
  • Retains stock 23 degree angle and intake/exhaust bolt locations
  • Does not require offset rocker arms
Assembly features:
  • 1.46" diameter dual valve springs, good to .650" lift (flat tappet cams)
  • Stainless steel 1 piece swirl polished valves
  • Chromoly steel retainers
  • Hardened steel valve locks


These heads will work for all small blocks including 400s (when not using steam holes, or when drilled by a qualified machinest for steam holes). Has the earlier style intake bolt pattern (pre '87) that had all bolts going in at an angle.

They will accept either 3/8" or 7/16" studs. You can also use standard off the shelf items such as pistons, rocker arms, guideplates, and stud girdles.

Aluminum material allows the benefit of higher compression ratios on the street compared to iron heads, not to mention that it saves nearly 20 lbs per head verses the factory ones!

These are a great choice and at a great price. Perfect for performance/race applications where a quality head at an affordable price is desired. 190cc intake port works well out of the box on engines with around 400-500 projected HP. Further gains can be had with gasket matching and porting techniques.
*NOTE: Due to the port size and location, most dual-plane intake manifolds will not cover the intake port completely.  You will require a large runner intake and corresponding intake gasket.
