Can I put 1.97 roller rockers on my VX V6?

You may put 1.97 extreme high ratio rockers on your vx v6 naturally aspirated and supercharged form (L36 and L67 engines), which also includes push rods, rocker bolts and pre-lube. Note: All rockers which have a ratio of greater then 1.9:1 are not really suitable for use with an aftermarket camshaft, as the many of them will create excessive amounts of lift causing potential damage.
