@Chris, It sure looks like hks cams
Its says hks in the cast and t083 has been drilled in intake cam and t084 in the exhaust cam,
wich says 264cams when I checked hks website...
Bought them second hand, they look very fresh...
I have to say I use wider feelerblades now, so they are as wide as the cam itself.
First I used a bit smaller and then 0,06 was like 0,10...
I have taken new feelerblades cause the small ones where like; 0,05-0,10-0,15-0,20
and the little bit wider ones where like; 0,02-0,03-0,04-0,06-0,08-0,10-0,12
