Looking for advice on cams, and why you would pick either or, so i can decide which route to go. HKS Step 1 cams (256, 11.5mm lift) or BC Stage 1 cams (264, 12.06mm lift). The HKS cams run about $230 per side and the BC's are $312 for the pair. I want HKS for their known quality, but i've also heard BC is a good choice as well. Do i pay for Reassurance or not? Thanks
