Pro and Con of Roller Rockers ? Questions

[Tim Cucci]

What would be the pro's and con's of roller rockers on a stock engine with stock P/P heads and stock cam and pushrods? Engine is fresh. Other mods below. Are there any HP gains to be achieved here? What are the con's such as fit and VC's and modifications? Which ratio would be best for my application? Are they worth the price for them compared to HP gain if any?
Thanks
Tim

in are low rpm cars you will see almost no gain. the only advantage is less wear on the top of the valve stem and
they provide slightly better rocker arm geometry.

Roller Rockers

Would agree that roller rockers would have a negligable performance effect on an engine that doesn't get out of the 5,000 rpm range. They aren't cheap for these motors, either. Money would be better spent elsewhere.

Thanks guys, I don't want to invest dollars if I am not going to get HP gains.

Thanks
