Looking at buying a set of these off a member here. Specs are 272 dur with 9.6 lift. I cant find any info on these cams anywhere. Would these be a simple swap of the stock cams or would there be any work needed to make them fit. Any info about them would be great.
I think these would go well with my 2860-5s.

You probably can't find any info on them, as HKS doesn't make them (at least not any more).

The only HKS 272 duration cams available are:
In 272° 8.7 lift, Ex 272° 8.7 lift – STEP 1.
and
In 272° 10.2 lift, Ex 272° 10.2 lift – STEP 2.

Hope this helps, more info at HKS's website

Having these fitted aswell
head needs work for them to fit mate
quite sure you need spings an retainers aswell

You will almost certainly have to relieve the area around each tappet bucket bore for lobe clearance, it's fairly straightforward on a Bridgeport universal mill or similar. Even I managed it and I am not an experienced miller

You can see the circular reliefs in the pic below. I can't remember the sized cutter I used, about 20 mm I think.

So it is just the inside that has to be milled, not both sides.

Both sides, the photo doesn't show it too clearly, sorry. This one is a BIT clearer
