Hi I just bought a set of crane cams adjustable push rods has anyone fitted these. And can you tell me if I need larger push rod tubes or will the standard one fit with out rubbing on the push rod. They're part number is 4-0030 thanks for any replies. 

Wazza , put them in, pull plugs out Plug the plugs back into leads get rear wheel off the ground, turn it over & check.

 

Thanks fellas I got a set of custom chrome tubes and only used the chrome pieces with the original top tubes and found it realy easy to install. It said to adjust the preload 3 turns but I adjusted them 3.25 turns as as the revs go up the lifters will not pump up as far and bleed down. But it's goo to hear they are a good set of rods. Picked them up from $80 new still in the box. Thanks for the replies.
