I'm using the Hughes 1.6 ratio rockers on mine. Had the Mancini "Harland" body ones on there for test sweep. I didn't care for the sweep pattern borderline outside IMO. The Hughes rockers are better. I also highly recommend the Hughes shaft hold-downs. Plus, make sure to get the longer studs- as mentioned here before. TF has them on their website.

My engine is a 400 zero decked with a .050 Cometic gasket; stroked to 470.
