Can you give me a little more explaination please? I'm a little lost. Not sure I get it, I'm just starting getting into the technical aspect of the mechanic. Thank you very much

on your stock 96 cid engine the intake valve closes at 30* ABDC (after bottom dead center on the compression stroke) giving you a corrected compression of 8.98:1 @ 184 cranking compression you want to try and stay with a cam that stays close to that intake closing for the engine to run optimum. or you will have to add a thinner head gasket and machine the thickness off the deck surface of the heads to achieve the proper corrected compression were the cam you chose runs correct. with the 574 cam the intake closing is 45* ABDC it drops your cranking compression to 171 and set your corrected compression too 8.46:1 which is less than you have now and will make the engine more sluggish in the lower rpm's. With that cam its needs the static compression set to 10.3-10.5:1 is were it will run the best. just trying to help you been there added a cam with a later closing and had to fix the problem

I am going to upgrade to the 107 S&S bolt in kit very soon which I believe will be closer to the ideal static compression you were talking about?

best pipe
I have a 2014 Low Rider with a HD Stage 5 Tire shredder 110 Race kit installed, used a Bassani Stainless 2 into 1 Road Rage III exhaust, fits great, look good, not overly long and sounds and performs great, very happy. Price was good compared to other options. I made a larger heat shield from 304 stainless to stop boot melt.
