Anyone farmiliar with hks camshaft types for 4age?

[spill86]

I have a set of cams that came in a japanese import ae86 with largeport head. They are both marked with the hks stamp in the centre of the camshafts and only one, the exhaust camshaft, is marked at the end and that reads 256 8.1. the inlet camshaft is scribed in the centre as 264 A with no indication of lift. Going from the only cam card for hks cams for the 4age i could find online the 256 cams only come in 8.0 and the 264 cams come in 8.1. Do i have acombination of old and new hks cams and am i reading off of the wrong cam card for the 256 exhaust cam. Does anyone run this combination of cams on a 4age and what are peoples opinions on running 2 different camshafts like this?
