That's why I gave em a call - The Primary "low" cam lobe is a tad larger than our current ITR cams. Its the Secondary "Vtec" Lobe 11.8mm - 254 dur at 1mm. (0.3mm and 11*degrees larger than our ITR cams)
I wrote down the full specs and will post em tomorrow when I'm back at work.

In essence I think the 176-B is a small stage 2 cam. Because its in need of aftermarket valve springs, where as most typical stage 1 cams do not.

SO the question becomes do we Upgrade our valve springs and waste all that work on a smaller cam (176-B) or go with something Stage 2

I don't think the 176-B will be the magical unicorn of stage 1 cams. By comparing against Skunk2 Stg1 its only 0.2mm and 2*degrees bigger on the intake cam. Maybe 2kw more lets be honest.

Valve springs not necessary for these- (Skunk2 stg1, Toda A, Blox Stg1, Jun Type 1, BC Spec 3+)
