Sorry to hear of your problems there Gordon.
Was the head not saveable at all?
Perfectly possible to recoil them or if theyre too far gone for that to tig weld the holes up and re do them that way. I could possibly repair it if you ever got stuck, just chuck a few photos my way and ill have a look.
Manifold presents a few issues due to its proximity to everything else, so any efforts have to keep the stock fitment positions and cater for improvements.
Ive just found some more photos of that tubular manifold and its been made the same as the stoc item, venting manily from the 5th cylinder- bad idea. I want my design to totally remove that feature and vent all the cylinders. Not easy but i think do-able.
Heres a prototype exhaust manifold i built for a celica turbo.
And an intake plenum for the same vehicle.
Did all the welding and powdercoating myself cos im like that...
