Hey guys. I am running a 429 ls3 stroker using the SDPC cncd ls3 heads. My cam has .620 lift with a 1.7 ratio rocker. I would like a roller tip 1.8 rocker if possible. I do road race the car. I run the engine up to 7000rpm. The car is a 2600lbs RX7.
What are your thoughts and experience.
I like the new comp ultra pros. But it seems like they will never be in production.
Design the cam for the rockers being used. puting a 1.8 rocker on a cam designed for 1.7 is not the prefered way.
Stock rockers with a trunion will do what you are asking

I have stock rockers with the comp trunion upgrade right now. I am just curious if the none roller tip causes crazy heat and side load on the valve. The engine does see a lot of rpms. I just want to make sure I have a very reliable setup.
