Re: lt4 valves

Are you looking for actual stock replacements - 2.00" hollow stem intake, 1.55" sodium-filled exhaust?

if I can find them for a good price, not $600. I will take anything that will fit at this point. I called Manley but I need the specs and all I know is the head diameters, they weren’t much help.
