Should I change out my valve covers from my chrome Edelbrocks that I had on or should I change to my Holley MT Chevy badged valve covers and if so does anyone know how to knock out the punch outs for my PCV valve and breather

I got my squarebody when I was 15 and daily drove it for 5 years, however recently getting a job in the bay area i drive a lot more now, so unfortunately it has been retired as a daily driver for now. At least ill have the ability to have it tore down for longer while I do the dually swap and put the new engine in. Lots to do but so little time to do it, slowly restoring, retrofitting, and upgrading

Front and rear seals leaking while I have it out would anybody know if it would be hard to switch transfer cases currently it has a np-208 and wanna put it my newly rebuilt np-205 didn’t know if I have to order a adapter plate for my Muncie 465 or not

Anyone interested this is my second square body I just don’t have the time and money to build both and wanna give the truck a good owner it’s a 1987 R15 GMC LONGBED with shell and carpet kit, 4-speed with a np-205 transfer case

Hey everyone I’m new here glad to be apart of the squarebody culture
