Yes, got your PM and a reply is pending.

I don't know if I'd bother with the AFR heads when there's so many good porting guys here in Australia. Initially I'll run the stock heads as they have some impressive flow numbers from the factory.

I'll probably get some heads done by Nathan Higgins down here in Melbourne. He's a well renown V8 Supercar cylinder head guy and has done a lot of development on the LS1 heads..

Clearance will probably only be an issue if I go for bigger valves or get too much material planed off the heads.

The stock injectors seem to run out of puff at around 500HP. I'm told you can go to 36 pound Ford Motor Sport injectors or 42 pound Bosch/Delphi items.

I'm looking at a new ECU development from Dicks Electronics. It's a factory Delphi ECU but it's been modified to incorporate an Ethernet port and real time programming software. It also does data logging at around 80 FPS. the advantage of this setup over LS1 Edit is that you can tune the thing with a laptop on the passengers seat. With LS1 Edit yo have to make changes to the code and then flash them into the ECU using a programming harness. You then check and see what difference your changes have made and tweek the maps again. It's all a bit hit and miss unless you're very experienced in tuning these things.

Cheers
