It's got ls7 lifters comp gold 1.7 rockers hardened pushrods and it has dual spring from
The previous owner if I had to guess there probably patriot (patriot heads) it's the only used thing I used when I built this motor besides the crank . I'll post the dyno graph in a little basically climbs to 400hp as Soon as it hits 5800rpm it levels out and the line is al squiggly lol

why would i switch back to stock rockers? I had stock ones on there when it was dyno. then i put roller rockers on because the bearings were going and its exactly the same just quieter

Normally when you have valve float there's a dip at the top end and then it nose dives off. It doesn't appear that yours is doing that. However your tq curve seems to be a little wavy. The local machine shop set my heads up wrong and I had horrible valve float. My dyno graph was really jagged and then dropped off.
