273 adjustable rockers to stamped.

So I picked up a 1967 273 that now has a hydraulic cam and original adjustable rocker. I know from experience that I suck at adjusting valves, so basically just want to set it and forget it. The cam is a mild Lunati. I have a set of stamped rockers and pushrods left over from a 360. Looking to find out if it will be a straight swap or if I need different length pushrods. Thanks!
