want to get my heads flowed or port bored. so who do you guys use?.
want a good job not just go there because there cheap.

 

We have used a couple of sources , both excellent....
CNC Heads - HOME and Roger Clark have supplied us both 2 litre and 2.5 heads.......

 

is there much to be gained by doing this?

 

On a built 2 litre retaining the stock cams we gained 50lbft on one car we fitted them to....Utterly transformed the low end of what originally felt like a laggy car....

 

 

thanks enginetuner

 

It's a totally worthwhile mod. I got my heads ported when my new STi6 block went in and the difference is amazing.

Now have a FMIC and it's not laggy at all down at low revs, probably because the engine flows air so efficiently (along with headers etc.) so turbo spools so quickly.

 

A porting job and Port Matching is always a good thing to do with mass produced castings like cylinders heads - good gains to be had.
