I'm rebuilding a Holley 80531 850 carb. The previous owner tried rebuild and put wrong parts in. The installed valve sizes are stamped H. Are these correct as the rebuild kit has 5 different sets and no specs for my carb?

ate you talking about the needle and seat assembly that works with the float or the power valve that screws into the metering block?

Is it a genuine Holley kit? you don't want to use anything else. ever.

Yes, the needle and seat for the bowl. And it is a kit from Holley, but it covers many different carburetors, but does not give the info for each carb. The previous owner plugged the primary power valve and did some other stuff that indicated he did not know one end of the carb from the other therefore I don't trust that he put the right parts in the right places.
