[wahlie]

so i pulled my valve covers off as i'm cleaning up my 350. I got the casting number behind the alternator and narrowed the motor down to an either 73 or 74 van/bus. My question on the valve covers.. The one had an oil filler cap and a pcv valve and the other just had an oil filler cap. Can I purchase a new set that only has the oil filler cap on 1 side and the 2nd valve will have the pcv valve?

thanks,
Chris
