need some help with cast #

I have in my garage a 389 tri power that was a project about 15 years ago. the intake manifold # is 541690. (just finished blasting it, got rusty sitting there with no paint) the 3 carbs i cant find any # on except 7011997 and 7019927 have 2 of 1 and 1 of the other. also the heads were completly gone through 15 yrs ago i remember they were comverted over to screw in studs with oil holes. casting # is 538177. they had new double springs with a dampner and new retainers. valves measure about 1.900 and 1.65 without taking them out. they were also new. question is what were these origianaly on and how much should i ask for them on ebay? thanks for your help.

Jerry,
The intake manifold is off of a 1962 model "541690".... i can't seam to find any info. on the numbers provided for the carbs. The head cast number is a standard head made for both 1961 and 1962 years. My info. shows the heads and intake came out of a Catalina,Bonneville,Star Chief or a Grand Prix.
