Im wanting to know if these could make some decent numbers. There are tons of engine ID sites but I never can find info I need. Any help is much appreciated..

This is the cast iron version of the Corvette/Z28, aluminum L98 head, you need to check the angle of the center intake bolts as this casting makes 2 part numbers one with the center bolts at 90 degrees to the mating surface for 1986 and earlier intakes it is P/N 10159552; the other is PN/10125377 for 1987 and newer intakes with the 72 degree angle between the bolts and mounting face. It is a decent head it is especially useful as a performance replacement for trucks that have TBI and Swirl Port heads as it is essentially the same as the SP head without the vane where the owner/builder doesn't want to go to Vortec heads with the attentive intake manifold exchange the Votec heads need.

These are a substantinal improvement over older the large chamber factory smog heads as well. Not as good as Vortecs and similar aftermarket heads , but not too trashy either.
