The rollers are less valve train friction. If your going to run 1.9 rollers i would also pick up L76 valve springs to go with them. If your going to run 1.9 modded ones you can keep your stock springs but, you wont be able to raise shift points past 5800, due to valve float.

The Plog is not a ported front mani - it is a Power Log. It is a replacement for the front manifold that flows better than stock.

To the OP: You are going to want the ER rockers for sure. They make more power on N/A cars. ZZP has a tech article on them as well if you are interested in reading it. You will also need a rocker install kit. You might as well replace the factory springs with LS6 springs too.

Another mod I would recommend with that setup is ZZP's HV3. Good for some decent HP especially paired with rockers and headers.

If you do those two things you should get some pretty decent gains.

ER rockers tend to add 15-20HP

You said they are ported front manis.. They are a complete redesign. Your post could have mislead him to think he needs ported manis, not a PLOG, since you said they were the same thing brahhh.
