Not that easy

If u are after a straight swap then forget about it.
it would be allmost a waste of time and money to by an different cam an just straight up pull the old one out and place the new one back it. i've got a mate that done it and he said that it does make a bit of a difference but all it really had done was make it sound tougher.

Your best bet would be to dial the new cam in and also to use a multi-keyway timing chain.
even with this i would also get the heads planed and do something about the intake system. and exhaust system.

plus don't forget that u'll hafta get ur 'chip' retuned to suit the cam.
anyway c how u go.

as for the roller rockers, leave them until u have a huge cam or soldi set up. the std arms are good to rev to 6200-6300rpm.

Yella Terra do a bolt on replacement roller rocker for the 304/308, 1.65:1 or 1.5:1(standard) ratio i beleive. roller rockers reduce friction in your valve train and may provide a marginal gain but aren't required until you build a high revving engine.rroller rockers work because they "roll" accross the tip of the valve stem whereas convetional rockers slide accross the valve stem tip creating wear/tear on both the valve stem tip and rocker face. standard rockers also create a sideways load on the vlave stem which creates wear/tear in your valve guides.

theirs no point in just doing the cam, do the engine as a package you'll like the results better. get some head work done, get a cam to suit the flow of the heads, make sure you can achieve the compression ratio required to make the cam work, bigger cam = more compression, exhaust/intake upgrades etc:yeah:
