TSR obviously worth considering or go a bit custom and go to Northallerton Engineering but... apparently one of their good guys left to set up on his on on the trading estate there. Apparently pretty damn awesome all lasered and sh!t. If you want i could get you some details so you can have a chat see if he can help with something particularly trick?

Very overpriced! Especially since its basicly a ported head which will cost about £300 to get done.

I thought that but it does come with extra gubbins like cams and lifters, still pricey though! For just the porting and valve seats northallerton engineering quoted me £200.

The new guy (ex N.E.) who was reccomended to me also in northallerton on standard way industrial estate is CAS Engineering on 01609 772421.  Now i havn't talked to them or used them so i would be interested to know how you get on.

Right. Seemed a nice guy and knew his stuff. He said that with a mild cam there is no need to port the head. He said it could even reduce performance slightly. He recomended to clean up the head (take off casting marks) and pollish it up then angle the valves. Then lighten all the bottom end.

i think the main area that needs doing on a kr head is the exhaust ports as there is like a right angle in it!! ive been having a look at heads in usa and you can get some very good deals, im not sure how much it would cost to get one into the country :undecided:

I'm going to ahve a go at my own!!!
My dad is a dab hand with a die grinder and said he will have a go at it! Apparantly the mirror polish reduces BHP, and you just need a finger smooth finish.

Looking for a cheap 16v head now!

even just taking out the casting imperfections appparently vastly improves gas flow. I'm sure it'll be obvious when I get it  :wink: :wink:

as far as i kno, you want the exhaust ports as smooth as possible,

and the inlets smooth, but not too smooth ie no casting imperfections etc as mentioned , as the roughness can help agiate the air/fuel mix, so its mixed better for a bigger bang

some correct me if i am wrong though :smiley:

I dont think anyone will correct you mate. From my recent experience of ringing round reptuable engine builders i found that opinions vary vastly! Some say do one thing and other say not too. It would be nice if we could compare the results of each companies work on a standard valver to compare the results. But thats not gonna happen. So i decided to go with the company that sounded like they knew the most and has some evidence to prove their results. So fingers crossed their magic will do wonders for my engine too. Im hoping for 195 bhp from my 2.0 na valver on its origional k-jet injection. Watch this space (or even my project section) for the results in a month or 2.
