The Comp Cams 4705 spring locators are .060 thick. I need them to be about .030. Does anyone see a problem with having them machined down to .030? They are hardened.

 

Don't do it. If you are attempting to adjust your installed height you should
use the +.050" locks instead. The installed height with the beehives and
stock valves with the +.050 locks is 1.75". You might as well use the stock
spring locators which are about .040". I don't like them, but there are lot of
installs out there and it seems to work.

 

OK, I'm currently using the stock LTx seats, didn't know they were .040. I'm also running a .050 longer valve stem. I will need all of the 1.8" installed heigth with my 605/622 lift camshaft. The .060 4705 just may work with my setup. Initially I set the springs up at 1.825" and may be experiencing valve float. The 4705's might just get me back where I need to be.



Thanks for the info.

When I bought my 1518 springs and hardware from Herron Performance, he sent me those locks. When I installed them and compared them with the locks that Lloyd installed on my AFR's, I thought they look funny. They also look like they would interfer with my rockers. Here are some pictures:

If you are running 918's on stock valves with the +.050 locks you have to run NSA rockers.

 

"If you are running 918's on stock valves with the +.050 locks you have to run NSA rockers."

why is that?

 

I'm assuming Lloyd used the correct valve length, so I guess I'll have to get some NSA rockers.

You can see it in the pics, the lock moves up to the point where there is no room for the self aligning tabs to stick down below the sides of the valve stem.

 

No... JUST RUN THE LOCKS LLOYD GAVE YOU! Your installed height will be jacked and the springs aren't going to like the +.050" installed height. If you have a +.050" valve you don't need +.050" lock. This is why you get a matched kit and not just something from a GP.

Roger that. I e-mailed Shon and he told me to send them (locks, seat and retainers) back and I'll get me another set of springs + the difference.

Thanks,

Why don't you just run the parts that Lloyd put on the heads with the 1518's? If you had beehives before the same parts fit them.

That's what I ended up doing
