$1595.00

MFR Big Block Chevy 345cc Cylinder Heads are clean cast aluminum square port heads that are done in house with a 2.3/1.88 intake and exhaust valve job. Flat tappet, hydraulic or solid roller valve springs,  Stainless Steel Valves,  10° locks, retainers, Dart adjustable 3/8 guide plates with 7/16 rocker studs. Tool steel light weight or titanium retainers are available. I use these heads personally and found them to be of the utmost quality castings and machining. These are not ProComp or Speedmaster castings.
