I agree with Sharif..........go with the Supertechs if you change out the lifters. They are a great product....and I am pretty sure they have a DLC on the lifter friction surface.
I am pretty sure they are not "billet" lifter though. I could be wrong, but they aren't machined from billet slugs.

my dissagreement is not just with the op but nissan as well.in a traditional push rod design,the camshaft "lifts" the lifter and changes direction at the rocker to "push" the valve open.there is no lifting going on,if anything it "pushes" the valve off the seat.the definition of lift and push are very clear on this matter.the fact that they dumb down the names of internal parts to help the uninitiated understand is not an acceptable reason for defying logic.if you look you can see that their incorrect labeling of this part only confuses some even more,considering his mind went right to a "hydraulic to solid" question and was being sold nail soup on this premise.i understand your point as to what the book say's but that does not make it right or common within overhead camshaft nomenclature.

When I had my heads ported and valve seats ground, I had them set up the valve stem height so that I can use the same size lifter for all the valves.......of course, this is assuming that the cam lobe base circle is the same at each valve.

what I like about the supertechs is the ability to buy a single part number for the lifter......and then buy shims to adjust for lash. buying lash caps is alot cheaper than buying new lifters everytime youe change your head setup.

I may have to buy a few different lifters, but the majority will all use the exact same lifter thickness.

I asume you live in Greece. If so you need to get a proficent mechanic to confirm that the noise you hear is indeed excesive valve lash.
If it is, the cams need to be removed & the proceedure outlined in Z1"s post #25 carried out.
If you rev your motor hard or maybe miss a gear occasionally & the motor o"revs, I would not use supertech lifters on the stock VQ valve spring & retainer as the top of the valve stem only protrudes a few mm above the retainer & the shim can dislodge under valve bounce conditions. ( for you doubters I've seen it happen )
Better to order the correct lifters from one of the Nissan parts sponsers on this site.
