Default v3 sti heads or standard-modified??

hey guys,just wondering what would be the best on a v1 cdb engine with forged internals.

the more "agressive" head with cams from a v3 sti

or

an aftermarket cam kit,although a mild one like tomei,(not a 272 lol).

i want that bit of extra power from the heads but dont want it to sound like a tractor either!

could i have a v3 head and cams modified with uprated valve springs and retainers and porting instead of going fully aftermarket.

what are your views guys?

cheers

Jamie

450bhp+ on a sc46 is the target.

Standard V3 STI heads will just about be up to that with the right mods & mapping etc.

V3 STI heads are well known to be the best for power gains on classics. At the level you are aiming for standard heads cams & valves would be sufficient. If it were me I'd save some money here to put into a fully forged build.
