Which heads.

Which heads.
Planning on building an engine to take 4/450 ish, thinking about having a set of heads built, ported and some fancy cams, valves etc.
So what i'm after is info on which heads to start with and what cams and valves to go for.
In the first instance I shall be fitting the engine into my 54 plate WRX Wagon PPP with a hybrid TD04 and then at a later date i'll stick it in my V3 Type R with a bigger turbo aiming for somewhere around 400bhp, not too bothered about numbers TBH just want it to come in hard and pull well through the range if that's possible.
I'm a virgin when it comes to heads, cams and valves so just want to know what heads would be a good starting point, or if I could just buy a cheap set of WRX heads and have everything done to them.
I'll not be doing a self build as I don't have time but i'll fit the engine myself so not interested in anything that's going to require looms/ecu to run avacs.

I'm running 460 on standard V3 STI heads cams & valves, but Paul Finch has advised me a set of Supertech valves would be wise especially if I push it any further. I think your biggest problem will be making the set up work in both cars but I think it is possible.

Just use the V3 STI heads?
Maybe a set of Supertech +1mm valves (Don't use their valve seals though) or even Crower. And a port and polish?.
I'm sure Enginetuner can tell you what standard V3 STI cams are good for.
* Although, will you hit a snag when it comes to HT leads/Coil packs when fitting it to the newage?

Use the classic heads & manifold in the classic & the newage heads & manifolds in the newage. This simplifies many issues, but there are other ways of doing it, plenty of people put newage engines in classics complete with manifolds it just needs some modifications.

Thank's for the replies guys, I think i'll have just the V3 heads done and stay with the WRX heads for the newage, just need to sort a set of WRX heads out so i'm not p!ssing around too much mybe get paul finch to port them and put some fresh STI valves in them as above.
Doing it this way because I don't want to drive it back to uk just yet as it costsŁ700 there and back.
Any one got a set of newage WRX heads going extremely cheap/free.
