Car is going into the workshop tomorrow to get the head swapped over with new seals/gaskets/big port cams ect.

Anyway, I'm going to have the Ignition Timing set at 12 degrees (stock is 10) but was wondering what the Intake and Exhaust should be? I remember vaguely that the Intake should be advanced 3 degrees and the Exhaust retarded 1 to make the most of the bigport cams? I've got TRD style adjustable cam gears (the one with the 3 pair of dowels for adjustment) so don't know how much adjustment can't be had.

Anyway, engine is a small port with big port cams with exhaust and intake mods. Any help would be awesom
