how well do these hold up compared to yellow terra or other shaft mounted rocker arms, will they hold my g5x3 (probably but just asking). How is the quality like?

From what i've seen in pics very nice. however I also saw a thread where someone had to trim the end rocker tails with 5.3 heads at the corners. I still wonder was this due to that particular casting or is this true with all 5.3's ???

I have HS rockers and 5.3 heads. No problems and I rev to 6800 at the track all the time. They were a drop in install. no trimming at all. They fit perfect and are great quality.

I would be sure about the results before I run those. Actually I almost installed it but I'm going to hold off until I get a setup together.

Ive got them on 3 cars now and fit is perfect.
Just before/after dynoed one today on a stock head z06 with cam and all the bolt ons.
Going from stock 1.7 ratio to HS 1.8 Ratio (220/224, .530 lift @ 112 cam)
Before : 392 RWHP
After : 396 RWHP
with most of the gain being in the high rpms...

The reason I'm asking is i'm getting some HS 1.7 with PP 5.3's stage II.
If I would run into the same problem as you did, I wanted to check out other options beside trimming the rockers.
