coil on plug?

Yes I had to change the internal return water hole above the thermostat in 
the block.
It is round at the WR but bigger oval in the head so material had to be 
added to the block to cover.
The cambelt were too close to the head so the lower tooth wheel had to be 
moved outward some mm
by turning the balancer in a lathe - and the 83 WR don't have crankcase 
ventilation at the block
so that have been added to the valve cover. (learned the hard way)
The 034EFI IIc have drivers strong enough for the coils in the AAN 
valvecover, so separate high output coils is not a must.
