I was wondering if a stock motor and intake with just cold air intake and nitrous benifit 1.7 roller rockers I have them allready from another project they where going to go but didn't THANKS for any input and would it give it any diffrent of a idle?

If they are free, then yes there is a benifit, less friction, due to the rollers, but I would not buy them to put on a other wise stock engine. the heads are the weak link on 5.0's, start there then worry about the cam, or 1.7's.
 
I have read in a few mags that putting 1.7's on stock heads with weak springs can be a pretty bad combo. I would just save them for when you get a set of heads. Even a set of gt40 heads with 1.7's is the same setup ran on the cobra's. Good luck
 
I have GT40P heads with the 1.7's and new springs and runs good. But I also read that weak springs with 1.7 will hurt power. I might have read that same article. I believe they put it on a 100k motor that was almost all stock and it lost like 10 hp I think.
