Not only do you get more performance out of the box than OEM heads, but they retain the stock look. As another benefit, you can run higher compression with these heads before the onset of power robbing detonation. There is absolutely no reason to rebuild a set of OEM castings when you can buy a better performing, higher flowing and more detonation resistant cylinder head for less money from us! To top it all off, we offer aluminum and CNC ported Cleveland heads for people looking for even more performance. INTAKE / EXHAUST GASKETS All stock gaskets will work with these cylinder heads. The exhaust side of the head uses standard 4v exhaust gaskets. You can use Speedmaster SM3274 or Fel-Pro 1416 header gaskets which measure 1.89 (W) x 2.19 (T). HEAD GASKETS The Speedmaster PCE281.1703, PCE281.1714, PCE281.1724 and PCE281.1726 cylinder heads use the following head gaskets for use with 351C block: Speedmaster PCE348.1005 (MLS 4.055 gasket bore) Fel-Pro 1013 (Composite 4.100 gasket bore) Both gaskets are .040 thickness when compressed. HEAD BOLTS / STUDS Use Speedmaster PCE279.1014. These studs should only be finger tightened into the block. Torque the nuts to stock specifications. using high pressure moly lube, in increments of 15lbs.
