    Anybody running the stage 2 Kelford camshafts ? Part # 247-B. I bought it used with around 5k miles of usage. I'm curious if it can be ran with a stock bottom end as far as the piston to valve clearance due to the increased lift and duration. I tried to search around but no info on these cams in a Speed3/6 motor .. Any feedback would be great. Kelford posts their specs on their website: https://www.kelfordcams.com/nz/247-b-camshaft-set.html
