Okay, I'm not sure what you were trying to say but I think I got the idea. The quote you mentioned doesn't say anything abt 87 octane.

A cam is less than half the cost of Rockers, and you get increased duration AND lift.
Rockers are more than twice the cost of a cam, and you only get increased lift, NOT duration.
A cam is slightly more involved in the installation, but not horrible. And it gets you in there to replace a couple other things that should be done anyway. Like the timing chain, crank sensor, and perhaps a water pump too.

A cam. But not by that much. Both are reliable. But the cam will produce better power every time.
So you can do a cam, water pump, and timing set for the same price as rockers, and get more than twice the benefit.

Cool but see here where I'm concerned.
It says that they recommend a higher stall torque converter. Should I do that? I don't mind replacing the timing chain, water pump, etc, they're due to be replaced anyway.
The new Stage 1X Cam is the IDEAL aftermarket cam for use with stock heads, lifters, rocker arms, retainers, and pushrods. The powerband is strong from 3,300 to 6,600 RPM, so you will want to use a higher stall torque converter, such as our INTENSE™ 245 mm. Extreme Duty Torque Converters.
IMPORTANT NOTES:
-We recommend that a new timing chain and timing chain tensioner be installed in conjunction with any new 3800 cam
-We recommend CompCams "OE R Series" Hydraulic Roller Lifters, High Load Valvesprings, and Valvespring Retainers with any aftermarket camshaft
-We recommend INTENSE™ High-Performance Pushrods with any aftermarket camshaft
-INTENSE™ Camshafts are hydraulic rollers, so no break-in period is required
-No PCM changes are required, however the INTENSE™ Stage 1X Normally Aspirated Cam may set an occasional *.E.*. light after extended idle periods and the Stage 2 Cam WILL set the *.E.*. light.
-Higher WOT shift points (6,300 to 6,600 RPM) and rev limiter settings will further increase the performance of the Stage 1X Cam. Stage 2 users will benefit by increasing those numbers by approximately 200 additional RPM and Stage 3 users will want 200 beyond that.

The higher stall converter is to take advantage of the shift in power. Mostly at the dragstrip in a launch. I'd say for a dedicated street car, you'd be just fine.
That'* a question for Rogue or Scott to answer in more depth.

Oh thanks, maybe a shift kit will help take advantage of that. In your opinion, do I need to get the lifters and pushrods, valvesprings? INTENSE says it is the ideal camshaft for the stockers but down further it says that they recommend you get pushrods, valvesprings, etc. Maybe that'* for the stage 2 cams.

If you've never tore into a motor before I would recomend just doing the rockers.
and IMO 1.8 would be perfect for someone who isn't trying to go all out on thier motor.
You can get re-worked stock rockers for $300 at www.wbodystore.com . And you don't need stiffer valve springs like you would with 1.9'* or a cam.
Your also least likely to need tuning with 1.8 rockers than a cam.
For someone who isn't a performance freak like me and just wants an extra kick in the pants without alot of hassle, I think it would be the 1.8'* anyday.
