The installed height is 1.930 and the pic on the left is with NO lash Caps and the pic on the right is WITH lash caps... I am using a .010 shaft shim here also! I have about .15-.020ish clearance using my eyecrometer without the lash cap and like where the roller wheel starts out on the valve also! sooooooo would you run it without the caps... Im thinking so but would like some professional opinions

(the rockers move freely by hand also rotating them on the shaft)(I also had to use the lash caps last time)

I personally like lash caps as it usually corrects my geometry issues anyhow.

when i was mocking mine up, when i used the lash cap it produced more lift than without. i was set up at 1.950 with smaller diameter spring. i did just touch the rockers with a sanding disc and everything was fine. i did'nt care for the pushrod to the cup angle with the lash caps. good luck with what ever way you go.

Im not trying to be smart, but that was your fault. Lash was way out if a lash cap came off... I been in your shoe's so I know what your feeling... I was disgusted, but only had to look in the mirror to see who was at fault.

I'd run the lash caps - with or without the clearance issues. One of the big draw backs to running roller tip rockers ( verses pallet style )is the high load on the valve stem due to the minumal contact patch with the roller tip. Lash caps help in that area.

Bob, you think Im not aware of that.. My point(Aparently overlooked by some)was that with the additional tiny parts added to your engine, there is always a chance of bad lash settings, broken pushrods,rockers,springs which in turn will cause lots of other problem including lash caps with nothing to hold them in place,Again floating metal objects in an engine that doesnt need them is Dangerous..

I had same issue with my T&D rockers on the Victor heads, used shaft shims and split one of the rocker stands.
If I did it again, i would get the heads bare, get longer valves to fit 2.0" install spring height, mill off the stands and use the maxwedge rocker stand blocks to raise the rocker shaft to the correct position.

Well I didnt wanna run lash caps simply cause the "extra" parts... and cause issues listed above! I really dont wanna grind the rockers also! sometimes I wonder what the hype is about TD's. bigger springs seem a pain! Never had issues like this with my harlands.... I'll just sick with the caps again

1. You can take the sharp off the spring. 2. You can run a retainer with a rounded edge. 3. You can run a retainer or keepers with -.050 and adjust the spring seat height accordingly. 4. Manton make keepers that are also captured lash caps, if you can get them in the correct height.

I like and use lash caps on all my solid roller cam motors, they work fine as long as you don't have a real loose lash cam and let them get looser I have had them come off also on the dyno when a adjuster came loose I now use Manton adjusters no problems like that anymore

We have used lash caps on several motors. Even the famous 572 lol...with no problems just check valve clearance when motor is at temperature. Check clearance often to catch any valve clearance problems.
