Well there in and run in. Spoke to a local engine builder ( the guys who did my head work ) and he said it'll be fine with used HLA's so I just fitted them on the old HLA's covered in engine oil. I ran them in for 25 mins at varying rpms between 2500 and 4000. I've Been thrashing it to death for a few days and took the cam cover off yesterday to check the lobes and it all looks fine. I changed the oil and filter just to be safe but there were no shavings I could see in the filter.
Cams made a decent improvement aswell so I'm happy.

It's one thing for you to take a gamble and roll the dice with used lifters.... It's another thing for a so-called "engine builder" to tell you this is acceptable.

So is this putting in new lifters with a new cam only applicable to using brand new cams? I know several people who have the exhaust-intake cam mod without putting in new lifters with no problem. The exhaust cams were already used at that point.

I won't name my engine builder as I'm not sure theyd want to be part of a forum debate but they are very very well known in the rally world and I have 100% faith in them. They have built engines for ari vatanen and have been around rally since the group b days I have no reason to doubt them and they're advice has worked fine.
