Default Yella Terra rockers for L36?

Well, I should be getting my taxes back soon, and I think I want to get some rockers. Does anyone run the Yella Terra 1.8 rockers in their L36? How well do they perform?

I'm assuming the 1.8'* on ZZP'* site that aren't named are also the same as the INTENSE listed YT'* for the same price with the same 'lightest on the market' tag line.

I can tell you (somewhat related) that I have the 1.8'* on my Series 1 from YT, and I run the same basic pushrod (same specs and manufacturer, different length) that INTENSE sells.

I'm very happy with this combination, and it made a noticable difference. There are some that say 1.9'* are too much for an L36, and that 1.72 does better. I presume the 1.8'* are a pretty good compromise, especially for the price.

I'd also presume some of the L36 performance guys are about to ask you if you're going to keep stock shift points or not.

Well, I have plans for a turbo later this year. But, I dont want to overdue the rockers on the NA setup for the time being either. There was some good porting done to my heads and LIM so it should flow good with 1.8'*, i think. My shift points were set to stock, but Ryan @ GM Tuners can adjust that. I need to have him burn a new chip for the rockers anyway. What should I be looking to do with the shift points?

ER rockers would be best but 1.8s are better than 1.9s.

I was kinda leaning toward the Yella Terras because they are an aluminum roller rocker whereas the ER'* are a re-worked stamped steel rocker.

Would the 1.9'* be too much for the N/A setup? I plan on going turbo, but it may be like a year or so before I get everything together
