Is it possible to fix the lash adjusters without removing the timing belt or at least releasing the tension?

I'd like to not have to tear it back down that far but my brain says if I don't release the timing belt - the tension on the cam is going cause problems.

I hate shops! I sent my heads in to to done and when I picked them up - I caught them with their pants down.

They had put one of the cams in backwards - of course they said I was wrong and they had done it right. But when I made them put the heads side by side it was obvious. You can get both right or both wrong- I told they were stupid when because one was completely backwards- they had the exhaust ports facing in on the pass head.

So they swapped it around- now after installing it- the noise from the lash adjusters is driving me crazy! So my project for this coming weekend is to adjust or replace the lash adjusters.
