Pushrods and ticking and coolant crossover for head
Okay I have a ls1 5.7 with 5.3 heads milled .020 comp r lifters. F1 cam .591 .569 on a 112 the head gaskets are the stock ones from the local orielys fel-pro gaskets. Stock bottom end. Stock valves in the 5.3s but a good valve job done. Also i am running 7.4 comp pushrods. I think they might be to long cause if cruising for a few minutes at about 50mph i start to hear a really loud ticking coming from the engine but wheni stop for a few seconds and start going again it clears up for a lil bit. Has to be either the pushrods too long or rockers are messing up but they look fine or my new $200 comp lifters suck.thanks guys for all the help you have been giving me. Also my radiator is leaking but i have a new in the garage but it doesnt have the line for the top of the radiator for the head return line. Can i just cap that off at the heads but still have it crossover to each head so it still flows. I noticed my dads 5.3 truck doesnt have this from factory. What do you guys think of all this.

If you have Comp R lifters like you state and 7.4" pushrods, you probably have way too much preload on those lifters from what comp states.

Damn so i should need the 7.35 instead right? Or what size should i get? Dont have a legnth checker and dont know how to do it. What about the crossover tube for the heads? But if i have that much preload then wouldnt i need a much shorter pushrod instead thanks guys
