[QUOTE="singlespeed, post: 87659, member: 264"] Just off the phone with Catcams UK and is sounds highly unlikely that the cams could be reprofiled and last any significant time due to the negative radius cam profile. Turning down the base circle would mean excesive backlash and the valve train would shake itself appart fairly quickly. They dropped the previously planned cams from their schedule because they were promissed a set of cams and head to play with but they were never supplied. Hmmm, I wonder where we could find a spare head and cams to send them :roll: Hopefully I'll have the head back this week and get it posted off. Expected lead time is up to 12 weeks but may be sooner if their existing K4M profiles work and just need the VVC drillings 8-) :mrgreen: [/QUOTE]
