ok, thx thats cleared alot up,jst a few more Questions if i can...

1.is the Egr such a big problem? can it not jst be not used or sumthing (really know nothing about this area)and im a little confused about adaptor plates , are they really that bad and not worth it??. i thought the Holley's Street Avenger would fit right on my intake or so i was told!?

2.and to be honest i have no idea what press studs or screw in studs are or do. is it really needed to change from press to screw studs and if so is this along the lines of what i need...and will they fit right on or does it involve machine work????

3.a performer rpm intake is not out of my price range, was jst curious about the above.
From the looks of it i want a very simialr setup to what u have and you say you got over 425hp??

The egr intake can be used, but I wouldn't use anything other than a Q-Jet on it. It's just you are giving up alot of power with it. For this type application, I know what worked best for me was the RPM intake. Since this is going in the T/A, then might even look at the air cleaner assembly from Larry (WFO) who is on the forums here just for the clearence under the stock hood and still look right.

Your current rocker arm studs are a press in style. Under higher lifts and spring pressure that goes with that, the stud can raise up out of position. Screw in rocker arm studs once in laced and torqued, stay put, there by not being a loose rocker arm issue later like a press in stud will be. The hole needs to be tapped for the threaded bottom on the new studs. On Pontiacs, the bottom is already a 7/16" dia., even the press in style. The studs you need are either a 1/2" bottom or you can get thew holes reamed/threaded for a heli-coil set up as some do for a 7/16" bottom also. The ones listed on your link is for a stronger factory replacement style ARP that has a 7/16" bottom.
