I will ALWAYS say that a better pushrod will always increase the performance of ANY ANY ANY cam.

Were any of those pushrods that were bent the same $40 LPE pushrods I used? I didn't think so. Perhaps the late John Lingenfelter knew of this and decided to go with something reasonably priced that WORKS?
As Walter Cronkite said, "And that's the way it is..."

Sorry... have you checked to see if the pushrods are bent? Regardless of whether or not you care it is a possibility the pushrods are scored because of deflection which was covered in that thread.

I had a similar problem with my car and fixed it with new lifter. I know you just put new ones in but that is the only way oil gets into the pushrod to get to the rocker. I would pull that lifter out and take a look at it.

One of the pushrods or all of them?

as for the ticking/knocking.... it was doin it with the old lifters and the new ones. So im pretty sure its not the lifters.
As for the pushrods.. all of them are getting oil through them, just not the one making noise. So i got 2 seperate problems with the one rocker.
So with all the old AND new pushrod/lifter combo, the noise it exactely the same. And i poured oil all over the rocker and the noise never changed a tone.

well i just took everything apart and its all spotless. Nothing is dirty and nothing clogging the lifter bores. Only thing i notice is the pushrods already look worn on that one lifter. As if its not spinning and that prob. because i got no oil going through it.

Did you take the lifter apart?

You don't mention what type of rocker you are using, but it might be worth swaping the rocker on the #2 exhaust where you are noticing the noise to another location and see if the noise follows... if so it might be wear in the needle bearings of the rocker (assuming roller rockers?)

ok, well i almost got it figured out. I took the one bad lifter apart to clean it out and check it all out. Everyting was clean or at least to my eye so i put it back and swaped it with a different lifter that i knew worked in my motor. Turns out that the "bad" lifter was the first to get oil to my rockers and then the rest was all good. So now i got oil going to all my rockers but still ticks the same even when i swapped stuff around. So im still not ruling out a exhaust leak so for the $20 im gonna change the gasket and go from there.
p.s. I didnt buy new intake gaskets just to check to i reused the ones already on there and it runs perfectly fine, lol. So i guess im not buyin new intake gaskets.
