Default HELP! Excessive valve tapping

I just installed some Type R cams in my B16 CRX. After the install, i went in to readjust the valves. They were set at .006 exhaust an .005 intake. On intial start up they tapped, but went away after oil circulated. After warming up to normal operating conditions, the tapping came back and didnt want to go away. So i readjusted them again when the motor was completely cold and set them to .005 exhaust and .004 intake. They still did the same thing!

Motor has about 40k. Motor tapped a little with the stock B16 CAMS.
Motor has I/E/H.

I was debating to run tigher or even .000 valve lash?? Wanting a second opinion or anyone who came across the same problem and has a resolution for me Thanks

Alright, i narrowed it down to the LMAS. Does anyone know of a way to solve this problem without removing the head and replacing them? Something to get me by? I cant really afford to down the car right now and kinda short on funds at the moment.

Im still currently driving the car and it runs great, but i just take it easy.
If i continue to drive it the way it is, will i screw my valve train or cams up?

Any info or pointers will be greatly appreciated

The LMA'S dont require the head to be removed for replacement. Always use oem valve lash spec unless running aftermarket then use their specs.

Since your using ITR cams, adjust the valves to ITR spec. Im pretty sure its the same though. Its 6am and my brain isn't working.
