Yes they will work. The roller tip contact pattern must be checked. It is very important or valve guides, valves and rockers will wear out quicker. Also check clearances around the pushrod holes, guide plate allignment, coil bind, between rockers and retainers. Make shure the poly lock clears the slot in the rocker. Push rods are the last componet you should purchase after the geometry check on any engine. This is because milling of the heads decking of the block etc. can effect any engines push rod length. Just know if you have purchased a .500 lift cam with duration of what ever with 1.7 the lift and duration will be less. If you have not bought the cam yet and you woulld want a .500 lift you can multiply the rockers ratio by the cam lobe lift untill you get .500

Example
1.73 x .289lobe = .500
1.70 x .294lobe = .500
IF you have already purchased a cam multiply lobe lift times rocker ratio to get your true lift.
Personaly I check the actual lift with a dial indcator at the same time I am using the checker push rod to correct the tip pattern. I am rather **** so I will check each valve.

 

the stud girdles are already in place and I got the cranes rockers for a smokin deal

 

Just remember when you are doing that, you are using lighter weight springs usually unless you have pushrods in all the lengths (in other words the adjustable pushrod checkers won't take heavy spring loads) and need to recheck them with the actual springs and pushrods that are going to be used expecially on canted valve engines due to the side load on the pushrods, they will deflect and cause some more loss of total valve lift. You will loose even more once the engine is running but it's amazing how much deflection there actually is on these engines which is why I always even on hyd flat tappet cams recommend .080 wall pushrods, and unless you have no choice go with 3/8" diameter pushrods min expecially with heavy spring preasures. (stock on a 460 is 5/16" which IMO is too small even on stock due to the canted valve design)
This is more of a continued discussion than applicable to the reason for this thread but figure the info should be added for people reading this thread looking for info so BIG66PROJECT don't worry about it just take it for the info.

 

The side force isn't a problem unless you are running guide plates. The OEM design works fine with pedestal mounts. It saves weight also.

 

I bought a set of comp full roller stainless rocker with locks for $160 shipped to my door, He said he paid over $300 for them and never used them these should work great on my 460? I guess I just don't understand the differance between 1.7 and 1.73 am I going to loose performance?

 

the difference is .03 (not bieng sarcastic, that is just the mathematical difference) what that translates into is, and I am gonna use my cam card here for this. intake lobe lift is .454 so with a 1.7 ratio rocker the theoretical valve lift is .7718, but a 1.73 rocker will give a valve lift of .7854 (both numbers are at zero lash, and no valve train loss) What this translates into for you is a loss that will most likely not be felt and would have to be on a engine dyno to actually even measure, my guess would be that your alt draws more hp than you will lose with the difference in rockers. The other majjor difference and why this has been brought up is the 1.7 is based on a chev head geometry and the angles between the fulcrum and the 2 tips are slightly different making you actually check and adjust for geometry issues and possibly use a slightly different pushrod length to get the roller ot valve contact pattern as perfect as it can be. I have also found that with some of the 1.7 ratio rockers the distance from the fulcrum to the tip is just enough different that it is physically impossible to get it exactly perfectly centered on the tip of the valve but usually close enough that on lower spring rates it never causes a problem, and infact have seen stock setups that were off atleast as much or more. It's more of an issue with a max effort race engine where you are looking for every tenth of a HP you can get to maximize your setup.

 

Right on monster. But wwhen you have fully ported heads and your shooting for a certian lift and duration a lot of power can be lost. If a longer push rod is needed and a stocker put in lots of lift and duration can be lost.

 

so be straught up with me monster sould I cancel the order on the comp 1.7's and order scorpion 1.73's I'm sorry I;m new at this and my engine builder tells me what to order but wasn't real specific on rocker arms
