Hello, they aren't cheap but I'm confident they do a good job. This is my second 1400 build and the first one is going well. They pressure tested the head on this build and found a leak, they have milled out the offending part and fitted a new core plug. I suppose if this detail had been missed it would have caused a lot of trouble further down the line.
Notes..
Cps for pistons, I have spare rods if you need?
I have the head gas flowed and fit 1600 valves.
