Hello everyone.
I'm building a lz24 for my 620 king cab. as of right now i have everything but I'm trying to figure out what head I want to put in. I currently have a u60 head i got from a friend. Head has work done to it I just don't know what. it has shims under the cam towers, a port job on the intake, Crane Cams cam # DA-272-2-10 NC and it also has 162-17-9. I also noticed that the head lash pad retainers are taller on the intake valve and shorter or sunken in on the exhaust side. Its open chamber but also looks like its been milled down quite a bit. i wanna run the head but my friend says that i might bend the valves. Z24 bottom end has dished pistons. Any help or info would be greatly appreciated thanks guys.
