I have had a set of harland sharp full rollor rockers [ i think that the name of them ] that where for my old pontiac 428. are these the same as the ones for the lt1's , can i just chyange the studs or something to get them to work. I thought the old pontiac studs where like two sizes 3/8 to 7/16 or something. I do think they are the 1.6.

thanks for any help
