351 heads screwing stuff up?

[todd95GT]

Be very leary of used or cheaper roller rockers. I had a set of no-name-brand rollers on my Chevelle. After a few 1/4 mile passes at the drag strip, I developed a hard ticking. This was a pretty reliable motor until then...well, I gues until I added the different rockers. I replaced the higher ratio with ones of the factory ratio. I didn't feel I needed the little extra lift they were giving as the cam already had over .610" as it was (it was a big block 396 Chevy motor). One of the rockers broke a chunk off in front of one of the roller tips that rests on the tip of the valve stem. After the motor grenaded itself, a teardown revealed that the missing piece was the cause. You get what you pay for. Try not to save too many dollars on cheap parts.
