PCE has already done the work for you; our Top-End engine kits will save you the time and hassle of mixing and matching components yourself. These kits are specifically designed to deliver the performance you want, at a better price than purchasing the parts separately. Kits include: Fully assembled PCE cylinder heads Intake manifold Valve covers Intake manifold gaskets Roller rockers Guideplates Screw in studs Assembly Specifications Max Lift: .550 Coil Bind: .740 Intake Install: 130lbs @ 1.8 Exhaust Install: 130lbs @ 1.8 Closed Sear Pressure: 110lbs Open Seat Pressure: 300lbs Cylinder Heads Suggested Parts Head Gaskets The head gasket we recommend for our 23deg. heads used on 327/350/383/400 SBC engines without steam holes is Felpro #1003. On engines using the GM 400 block, or aftermarket blocks with steam holes, use PCE PCE348.1006 or Felpro #1014. Push Rods Our aluminum 23deg. heads typically use +.100" (longer than stock) pushrods, Depending on the components used, it is possible that you may need pushrods shorter or longer than that so we recommend that you use an adjustable pushrod to dial in your rocker geometry and order pushrods to match. Spark Plugs All PCE 23deg. SBC heads use standard 14mm. x 750" reach, 5/8 hex, gasket seat sparkplugs like NGK R5671A-7, Autolite 3924, Champion RC12YC, etc. Remember that higher compression/ boost require a colder heat range sparkplug. Head Bolts / Studs Our 23 degree heads utilize standard head bolts or studs. Our part number for head bolts is PCE279.1002, and the head studs are PCE279.1001. For the 15 degree heads, we recommend SM2451-15DEG. headstud kit with 3/8" reduced shank on the studs between intake ports. The ARP head bolt part number is 134-3601, and ARP head studs 234-4301 for the 23 degree heads. ARP also makes a head stud kit that is compatible with our 15deg. heads on cast iron blocks with part number 234-4723. Exhaust Gaskets We recomend the use of our Exhaust gaskets # SM5120 or Fel-Pro #1405 on our 23 degree heads. On our 15 degree heads, use SM5121 or Fel-Pro #1409. Roller Rockers Information PCE High Performance Aluminum Roller Rockers are extruded from 6061 T6 Aluminum. The larger needle bearing fulcrum can withstand valve spring loads up to 350lbs. Ideally suited for use with flat tappet roller cams. They feature very precise valve operation, horse power increase of 10-15, increases valve train life dramatically, acceleration is more responsive, oil temp will run approximately 5-10 degrees cooler.
