A roller mioght be my choice in time, like I said, I'm still considering my options. But I'm not afraid of installing a flat tappet and am confident it will live. They've been around a long time, it is proven technology. It's all about making the right choices for the parts and proper breakin procedures. Yup, a lot more work, more risk, more maintenance.
If I was an engine builder, I'd highly recommend a roller to MY customers as well. But I wouldn't do it using scare tactics and I'd install what ever cam the customer wanted.
On the street I rarely shift above 5,500-5,800 rpm, which is within range of a roller. On the track I like to shift at about 6,500 rpm. I love that high end and the feel of the motor that just keeps pulling! I actually LIKE the idea that I have to check my valve clearance from time to time, keeps me in touch with my motor. I guess I'm a dinosaur too.
It's frightening that you guys would install a hydraulic roller without breakin' lube on the cam and the rollers, by the way! As well as break in additive for the motor in general.
