bp blocks are longer due to the different bore spacing.
if the engine is a bp (engine number should confirm) then an bp cams should be able to fix with some work on valve clearance.
Also rather than buy from Japan think about buying local. Tighe do cams for under 800 a pair based on using you're stock for base material and about 1100 for new billet items. obviously you could get the profile tweaked to suit I'd they are local.
Finally, more than,9mm lift requires new springs. Depending on how old the engine is the valve springs may have softened anyway.
Single spring set up would set you back 400 odd to suit 10MM lift.
Yah that was me with the exhaust. Saw your car last night at jdmst too.

The NB6 block is a B6 block, I know because it's head gasket is the same as the NA6 B6 engine. So the only difference is really the head or maybe just the components in the head.
Will also look into getting custom cams made here, there are heaps of options I suppose. Just haven't done the research yet.
I was thinking of doing the ITB and MegaSquirt stuff first and learn how to tune it. Then later down the track I'll get the cams made along with getting a worked head. Just slowly build this car, I'm in no rush and have a daily car so allllll good!
