I have seen adjustable roller rockers and am wondering what they are--or in other words what is the advantage of them. Are they worth it on a high hp motor?

 

O yea and should i go with the 7/16" studs? They just bolt in or what kindof modification to install them is there?

 

What would a 1.7 ratio do? or is that too much?

 

O yea and can i use stock springs? Sorry so many posts......i keep seeing things as i search

 

Keep searching and you'll find all the answers too

1.7 would increase lift over then 1.5 stockers

you will need likley new springs

for 7/16 RR you would need new studs - stockers are 3/8"s they just screw in.

 

I know the stock ones are 5/8's but how do you use the 7/16 without machining?

 

Both stud sizes have 7/16th threads into the heads.. it's the UPPER [where the rocker goes onto] that are either 3/8" or 7/16" so they just screw out and the new ones screw into the same sized threaded holes in the head...
