So taking my calipers apart for a full strip down, am on about the 4 bolts keeping each half together... I slightly damaged a couple of the heads and one completely ruined so will have to drill it out :/

Anyway... have had a look on ebay, Rick o, David Silver, weemoto etc and cant find any replacements... anyone know where I can get replacements or anyone have decent ones I can buy?

Tried probolt?

Just had a look at their site, damn, you could spend a lot of money on fancy bolts haha.. no actual listing of the ones I need though, will have to try have a measure up and just try get something similar I guess?

They are available from David silver spares part no. 90107KV3701.

Some folk replace them with a2 stainless Allen bolts have done so on an rrx blade before then got told these bolts must be high tensile which the stainless aren't didn't have any issues with them at the time however wouldn't take the chance again.
Try lings for originals possibly the same as pre 98 blades and some other honda models of that era
Whatever you get ensure their high tensile you don't want the calipers splitting under braking could be rather interesting...

Ok great, cheers for the advice guys, will grap some from david silver now, trusting they are right parts, description on site is a lil vague but I trust ya haha thanks for finding the part number for me :)

Is it worth loc tightening them when I put new ones back in? It seemed the ones I removed had some kind of sealant in the thread?

Just looked and was about to post the same part number as above. You will probably find they have threadlock stuff on the the threads. Sometimes it's blue, sometimes red, sometimes green. Seems to depend on the maufacturer (it's not just a Honda thing).
