[Healeys] Re - 100 Alloy head

[mike brooks]

Changed out my cracked 100 BN2 head for a Denis Welch standard aluminium head. Used their steel gasket. Just bolted it on and adjusted the tappets. However I had very recently rebuilt my H4 carbs and it wasn't running well , so I ended up retuning these as well. Apparently Denis Welch use 3000 valves in their 100 head which are slightly larger so I wonder if this also means that carbs have to be retuned. I'm still on standard needles and springs . Running very nicely now,  although tends to minor stuttering when cold which disappears completely when warm.
