when i got my truck it was tapping loud wouldnt stay running had no power i barely made it home. i pulled the valve cover and found rocker arms laying in the top of head. i had valves that wernt even opening i mcgyvered them back in place and did a valve adjustment.. ran ok but need a new head. i was trying to burn out on a dirt road and she took a dump on me and started backfireing out the carb parked it two years later i blew up the trans in my toyota corrolla and now im mobbin my chevrelegs because both my vehicals are down. i need to get my truck going.asap i will post head numbers and picks shortly im going to pull the valve cover real quick and see what happened im guessing rocker arm is wedging a intake valve open. fml i love that truck

i am about to remove my l16 head and install a L20 head is there any problem with doing this?
