Have a set of 1.6s on my engine.

Going from SFT to solid roller. Dwayne Porter said to make sure they would handle 600ish lbs open.

Called HS, tech said bodies are good to 1200 lbs open pressure, but, anything over 600 lbs pressure he likes to see extra attention to oil flow to the rockers, or use a rocker with bearings.

Asked the tech if grooving the shaft would be sufficient, he thought it would be a good idea, but would not give a yes or no answer.

Has anyone been running these rockers on a roller cam setup? If so, any insight to how the shafts/ pivot openings are holding up?

Having to buy new rockers and shafts are a deal breaker for my build. I want to go roller, but it seems like the budget is on a steep trajectory. I'm not sure the gains are going to be worth the price.

Any input appreciated.
