I don't believe there's any specific #'s involved. Just general ballpark guidelines. Personally, I wouldn't use a stud girdle on any flat-tappet setup, hydro-roller, or "street" solid roller. Just make sure you use good 7/16" studs.

I don't see any need for girdles with that cam, unless you are running old GM aluminum heads. Again, use good rocker studs.

I'm running one with a solid roller if for no other reason than insurance.
My screw-in studs are 3/8" so thats 2 reasons.:clonk:

I agree. Use some good 7/16" studs and let'r eat.

You should always use them on aluminum heads,They will flex trust me.
When a rocker stud breaks at 8500 rpm you will wish the girdle was there to at least try to hold the stud in place.
It's pretty impressive what a rocker arm can do when pinched between another rocker arm and a set of $375.00 valve covers....:yes:

 

[Bob West]

I dont like them, I dont like adjusting valves with them, builder puts it on, Bob takes it off

Making sure you have the matching valve springs may be the single most important item.As Bob said,girdles are a PITA.

kida??? Is that some kind of ******* kung-fu??? :disco:

I had 3/8 studs with my solid roller, and I found I was losing valve adjustment. I installed a Moroso stud girdle the one with the U bolts, and it was easier to adjust my valves and they stayed adjusted longer.

When I first started adj. valves with a girdle it was a hassle but for some of reasons already mentioned plus a few more I'm glad I learned to adj. with girdle cause now its a piece of cake! Really! Anything less than 6000 rpm wouldn't use one but on a serious race application with rpm's up to 7000 and above use the girdle!

Ha,I'm sure that is a pain in the arse,take the girdle off adjust the valves and then put it back on your done.
With the four bolt kind it's about an extra 30 seconds per side.
That's funny **** right there bob.

 

[Sandy]

Warped, on a big block you don't take the girdle off and on cause of the valve angles.

I don't mind adjusting valves with the girdle.

One less thing to worry about, knowing that the stud and rocker are going to stay put.

 

[Jebchevelle]

well I was told I dont need them and my cam is close to yours a lil more duration on mine.
.660in/.630ex .270in/.280ex duration on a 110 lsa 106icl. I was also told to ditch the crower rev kit I bought builder said I wont need it plus I bought the worng one mines for regular roller lifters and mine are .300 taller isky red zones.
