the ratio stock im not sure, but i think it will go good with your combo, well im hoping it will because my combo will be much like yours when i get my car back......BTW, i noticed you have a 75 shot but your times are 14.3's....are those with the shot??? i thought it would be that w/out it.

1. 1.6 ratio for stock rockers
2. How many miles on your stock heads? Sometimes old springs can't handle the 1.7's. You will lose poweer if they can't.

I agree with Fasterdamit. I dont think it will do anything for you. Save your money for some heads Jared.

144,000 miles on the heads, should I just get new heads so I dont need to get new valve springs too because I dont want valve float with those rockers.

I dint really notice it getting any louder, it just feels better and more opened up. Actually now that i think about it it was little louder on the freeway say around 70mph than with the stock headers.

Headers and heads do sooooo much for 5.0's. Those would be some of the first things I would do!!! I beilive on a 5.0 heads and headers are one of the first 5 things that should be done...but what do i know?? I just hope to be shooting for more then 500hp soon. Do heads and headers, Long Tubes also are hella good!
