John Kuiper, 9 out of 10
Westend???... well, Sam is a good and careful machinist as long as you have lots of patience. I have been waiting for 6 months for him to machine a 308 for me. Lucky my customer is very understanding and his car still at the painters.
I would highly recommend Duncan Foster at Moorebank. I have been using them for over 10 years, average turnaround for a complete job like chemical clean, bore hone deck fit pressed pistons full balance on a short assembly never more than 1 week. Price is a bit on the high side but you get quranteed quality.
I do all assembly and blue printing myself.
