    Description

    This ad is for a pair of  complete assembled aluminum Oldsmobile cylinder heads for 350-403 & 400-425& 455 engines.  These are cast from virgin A356 aluminum and are heat treated to T6 specs. They are manufactured using their gravity casting process, which ensures a more uniform and robust casting. This provides a strong platform for you to build on. They are designed for high performance, are non-emission, 1965-1976 Oldsmobile 350-403, 400, 425 and 455 c.i.d. V’8s. The valve train has been upgraded from the factory pedestal mount system to a 7/16” screw-in stud and a 3/8” pushrod slot guide plate for increased valve train stability.
    This complete assembled pair of heads includes the following premium ProComp components: ProComp 2.075, 1-piece stainless steel intake valves and ProComp 1.680, 1-piece stainless exhaust valves, 1.460 o.d. dual valve springs, which are 130-135 lbs. on the seat & 320 lbs. open @.600 lift with Chromolly 10 degree retainers, 10 degree machined valve locks, & over the guide stationary valve seals with heat treated valve spring shims. We feel that this is an affordable aluminum head for the Oldsmobile Street/Strip (Bracket Racer) and marine enthusiast
    .
    These heads are similar
    to the Edelbrock Oldsmobile cylinder heads, at a much reduced cost.
