STD Reproduction Panhead Cylinder Heads

Since good, original heads are becoming more and more scarce, STD reproduction cylinder heads are a great alternative for stock replacement or for performance engine projects built from scrap. They feature many improvement over the stock counterparts like a raised port design for improved air-flow. Valve seats are altered to accept Shovel intake and exhaust valves and made of hardened material for the use of unleaded fuel. To allow porting and flow-bench tuning, the combustion chamber and inlet ports are unpolished. STD heads are supplied as pairs without valve guides and head bolts. They are machined for 1948-79 Pan/Shovel valve guides. For improved dependability STD heads come with steel inserts for the head bolts that accept factory thread 7/16-20 head bolts. All versions accept modern spark plugs with long 14 mm threads.

OEM style replacement heads feature:

  • stock Panhead exhaust flanges
  • stock Panhead intake manifold flanges (O-ring style 1955-up)
  • stock oiling systems
  • head bolt patterns for stock Panhead cylinders
  • single spark plug design

  • stock Panhead exhaust flanges
  • Shovelhead intake manifold flanges (O-ring type).
  • both inside and outside oiling systems
  • head bolt patterns for Panhead and Shovelhead cylinders
