thats determined by the people doing the head.
And also the lift specified.

Yes but the valve still needs to be able to seat correctly. I must find out more about this.

I say get a quote from Sportflow to do the head and maybe larger valves if there is room.
I have a flowed CA18DE head that has a slight leak on cylinder 4. Can be fixed apparently. I'd be willing to let it go too
When you do the headwork, you can always add a CA16 inlet cam for extra 0.8mm lift and 8deg more duration.
If you're lucky enough to find a pre 90 model CA18 inlet cam it has 256 duration.

Which ones? The late model CA18 cams are supposedly the same as the det. All exhasut cams are also the same fro all CA16-CA18De and Det afaik.
You also need the CA16 cam gear else your timing is nearly a tooth out.

But What do you guys think of ARP head bolts
Surely you mean Head studs?
How many sets of billet cams do you want and in what duration?
R4000 a set

Good to hear Calibrator, Maybe you can help me out in my new post.
Calibrator do you still have that set of cams for R 3000 ?
I have a Ca18DE (Jap Spec) cam, it has a longer duration then the Ca16de cam and the same lift.
Also you only need to go a tooth out when you use an exhaust cam on the intake side

Yep there was a nice gain...
