TVR did most of the work on the heads for me when the car was first built.  I just had to tidy them up & fix the bits they didn't do right...

What lift are you running with that cam?  I've just got a H404 from V8D for mine & I'm a little concerned for my pistons now!

Doesn't sound too different to mine. 

I wish I could find some cheaper roller rockers than Yella Terras to go with the cam...

have you tried summit or jegs?
can always ask on my v8 forum if you want to mate.

i made up a patch lead for the a/f-egt gauge today so it can go through the bulkhead with the other cables, i hope by making this extention cable it don't effect its workings,
also made the cable outlet hole on my gauge pod bigger to allow all the cables from the gauge to go through,
i made a sleeve sheath up to keep cables tidy from pod to behind the dash.
will put pictures up before the weekend,

Cheers Rob,
yeah have a few tweeks to do aiming for a 12's pass in july, but otherwise the car ran faultless.
would i benefit from the 16x16 table? to get an even wider range of fine tuning mate?

I wouldnt have thought that 16x14 would give you any advantages unless there are some parts of the table that you find you just cant get a clean transistion on.  One of the blokes on the mainland reported that he only needed to use an 8x8 table when running AlphaN on his BMW!

just an update,
car is running nice,
then dnb took a look and got her running even better (and he is still working on the settings for me to get her better still, top man) this where we have now found the poor factory injectors are not coping, eh Dave ;D
bigger injectors now needed,  8)

I've already put a post in the config forum to make sure I've thought of everything.

just getting ready to upgrade the injectors to bosch greens, (440cc's)

they arrived from fiveomotorsport in the states yesterday (monday)
dnb told me to use a transient suppression diode, has my ecu already got this fitted Rob when you built it?
If not what do i need to get, as i got an account at maplins and rs components,

It certainly wouldnt have come with one as the transient diode wasnt an option back when yours was supplied.  I'm not sure what happened with it when it came back to me, as I've slept since then.

This is the diode you need:
