Default 5.3 heads with offset rocker arms

so i read somewhere that the 5.3 head uses offset rockerarms. is this true? i am about to order me some PRC 5.3 stage 2.5 heads and i need to know if i can use my stock LS1 rocker arms. when i called TSP and told them i was planning on getting these heads they didnt mention it so i assumed i didnt need the offset rockers, also it is not on their website. so do i need offset ones for these heads or can i use my stock LS1 rockers safely on the PRC aftermarket heads?

I have those heads and the are not offset,,and yes you just use your rockers and pedastals no problem. Now you may need different pushrods,,better measure to be sure.
