I'm having trouble finding a good 731 head for my M20 rebuild. Maybe its due to my location, or popularity with the 2.7 stroker conversion, but there is nothing around right now.
I am considering buying a new one. ECS/Turner have them all. Who here has purchased a new M20 head, 885 or 731, in recent years? What is the quality of them like?
I don't want to buy a genuine head and find -despite the BMW logo- they are now manufactured by AMC, as this would be a step down from original quality.
I did find some new-old stock with build dates in the 80's, but they seem to have been sitting on a warehouse shelf exposed to moisture corrosion for the last 30 years, with pitting in the combustion pockets e.t.c
