question about rocker arms
I am building my head and bought some crower turbo cams and was wondering if I should spend the extra money on new rocker arms to be sure I won't eat my new cams.Or should I be alright? Does anybody have any feedback?

u will be fine. if u are running an ls head and running dual valvesprings u will eat rocker arms. the ls oil pump can't keep up in high revs, so everyone swaps in a vtec oil pump. u can use any gsr or type r oil pump. vtec oil pumps have a higher psi flow rate and will keep the ls head lubed properly. good luck
ps: u'll benefit the most from these cams if u upgrade the rest of ur valvetrain. dual valvesprings, retainers for higher revs. just a thought

BTW, the vtec and non-vtec oil pumps are the same. Only the years make a difference. From 96+ they are all the same and the LS doesnt like to keep up because the head doesnt have a very good oiling system for the cam lobes/rockers....unlike the vtec engines where it dumps tons of oil from the girdles on the top side.

yes if u want to get specific with what year oil pumps. main thing is run a vtec or 96+ oil pump. now not totally true about the ls. due to the oil pumps much lower relief spring in the oil pump it does put out less oil pressure and does not keep up in higher revs where an upgraded valvetrain thrives. now it is partial due to the design but the MAIN reason is due to lack of oil pressure to compinsate for lack of oil flow in the design of the head and oil pump where the extra strain due to the dual valve springs. don't forget honda did not intend on this engine reving that high. read up on the ls-t thread and u will see more examples of this. stock ls oil pump and higher revs in an ls head (8k redline) WILL eat rocker arms/pivots. just to clear somethings up for everyone
PS: type-r oil pumps are the cheapest vtec oil pump or 96+ oil pump available
