Default Camshaft question

Installed a Comp cam, .614/.617 227/231 lsl lobes on a 383 with AFR 215's, Fast 102 and NW 102 TB. Any issues if I decided to run 1.8 ratio rockers? Theoretical lift in the .650 range Thanks

You''d have to check piston-to-valve clearance to be 100% sure of no issues. Also, there might be an issue with too much lift for the valve springs.

His 383 is likely to have valve reliefs, but most ptv would be from larger intake duration or a the LSA and ICL of the cam. Not due to more lift with the rockers. Most companies wont recommend using 1.8s but I say go with what you want, but buy a quality rocker and make sure you have a decent set of springs for them.
