Small Block Chrysler Performer RPM 63cc Aluminum Cylinder Heads
Outstanding features include phosphor-bronze valve guides, interlocking, ductile iron valve seats, and premium one-piece, high-flow stainless steel intake and exhaust valves. Heat-treated and machined steel retainers and valve locks along with heavy duty valve springs are good for .575'' lift cams. For compatibility with aftermarket parts, these powerful heads use the stock location for intake and exhaust bolt holes and flanges, spark plugs, and valve cover rails. The special valvetrain in the 1970 340 T/A is not compatible with these cylinder heads.
Tech TipTo gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs, such as the RC12YC (P/N 192-49776). They are 0.230'' shorter than conventional spark plugs and have a 5/8'' hex for easier access.

Specifications:
Is it $867 for two or just one head? If so is there a cheaper alternative that would still work with at 1983 318 but would still also would with Edelbrock Performer Power Package Intake Manifold, Carburetor and Camshaft Kit Small Block part# 350-3776PK
Are the valve’s faces and valve seats hardened to be comparable with unleaded fuel?
So if I get 2 of these thinking one for each side for my 1987 Dodge D150 pickup 5.2l 318cid these will fit perfectly? How much more of a performance would I be getting for stock 318 head just looking for guesstimate.THX
Will these Heads edlebrock- 60779 work with the stock cast Exhuast manifold
What's the weight of these heads separate
Do you have to use an edelbrock intake with these heads or will other intakes work?
CAN I USE PUMP FUEL and what octane. 11&1/2compression
