[WaltZ]

do January 69 z28 heads have pressed in rocker arm studs from the factory or were some screw ins?
Thanks in advance

Screw-in studs started with the 1970 Corvette LT-1 and Z28 350 C.I. small blocks. A lot of conversions to the threaded studs and pushrod plates over the years on 186, 291, 461/2 heads for high performance use and reliability's sake -
