Roller rocker arms and pushrods

Thinking about further moding my 2000 gtp over the winter.
I have a 3.4 pulley on it Intake and dhp Pcm. I was wondering if anyone had experience with roller rocker arms and pushrods.
I was thinking about the 1.9 but then would i have to get new valve covers?
I dont want to have to do that to save money and i dont want anyone to know they are on there when they pop the hood ;)
What would you suggest?

Also did i go overboard with the 3.4 pulley? and could i get a 3.25 with the roller rocker arms and pushrods on it? If not what would i need to run an even smaller pulley?

Go with the 1.8 aluminum roller rockers. It is a one day bolt-on job. The 1.9 requires stronger valve springs (valvetrain mods) and then you may get premature wear on the camshaft. I have the SLP 1.8 and pushrods.

No. The 3.4 is the most popular and standard undersize street pulley used. The 3.25 will work fine too but you will need to keep a close eye on knock retard (KR). More exhaust mods like headers may be required. I have a modular SC pulley system and switchout between 3.0 and 3.25.

Also, a CAI/FWI and a bigger/polished throttle body either Stage 1 or 2.

Thanks a lot man. Just to verify
I wont need new valve covers?
Cant see under the hood?
Also what website or store did u get these from and what kind of power gains am I looking at?

You'll use the stock valve covers. Completely hidden and out of sight.

Advertised 15 - 20 hp gain for a L67 GTP. You will feel it in the seat of your pants.
