OK, so I am finally getting tired of retightening header bolts. Thought it would be ok - but after doing it every 2 weeks for well over a year - finally got old.
Browsing the Summit Racing catalog, I see several variations on a theme....but they are all LS1/LS6. Are these the same as LS2?
I tried a search - but searching on headers and/or bolts - you get the idea. Adding "retainer" to the search resulted in 0 hits.
I bought some stage 8 locking header bolts for my not yet installed headers from Maryland Speed. If you check their site, you should be able to find or deduce the correct info.
Sorry I can't give you a direct answer, but it is definitely a starting point!
