are the 430 rockers interchangeable with the 455? If so do i need to modify anything? I have a set of aluminum 455's, steel 455's and a set of springed 430 rockers. I am trying to figure out which one's to run on my car. Thanks Dustin
There was a thread about this awhile back. The Aum. ones had a slighter larger ratio but some reliability questions. The steels had the same ratios (as eachother) but 1 type came in directional offsets (w/ L and R on specific rockers) and the others (which I run on my 72 heads) were directionally neutral.
