Specifications:
Where are these rockers made? In the usa ?
Do these require guide plates?
How much thread engagement for the rocker lock? I’m referring to the Allen head lock screw , not the adjustment nut.
Will these work on 882 heads with this cam kit https://www.jegs.com/i/Lunati/638/10120701K/10002/-1 It’s a l48 350, do they need to be self aligning or do I need to purchase guide plates
Are these 1.52, or 1.5 rocker arms? Gets confusing to see them in different places with one of those two specs. Thanks.
WILL THEY WORK ON MY CAMEL HUMP # 39117291 HEADS?
Will they work on blueprint heads H8002k.
are all rocker arms smog legal?
