Wow ... this is a thread terrorist hijack ... settle guys.
I've sold 70's guitars some Kolben Schmidt 10563 pistons (72/74 124 coupe 1800) 5.2mm dome in 84.6 oversize like he wanted ...
Now all he needs is a regata100s head to complement the abarth 068 cams / vernier cam gears and 44IDFs he has for his build...
So the forum does work to put enthusiasts in touch with each other and move parts that are surplus to requirements... happy shoota
70'sguitars ... the thread about porting I mentioned during our 'phone conversation is here...viewtopic.php?f=2&t=2849&hilit=porting
it explains why the 100s head is IMO the best starting point for a performance build...
more general porting / head flow info (about sohc - but the ideas apply to the dohc) can be found in the X19 section too.
