Default 454 Mag EFI Cyl Head

I have a 2000 model 454 Mag EFI 385hp that is tired. I am going to build a slightly larger engine, but I need to know if my heads are oval or rectangle port, as I am going to use my current fuel injection setup with a new program. I would like to build the new motor before disassembling the old one because it is still running.

Thanks

Friend of mine is in the same boat here. He's considering a cam & possibly a stroker kit. I guess he'll have to reprogram the module if he does any of the above?

If he changes much of anything, he will need to have the ECU reprogrammed. Costs around $350 to have done
