While the engine was out of the car, I removed my built head and sent it off for a quick check-over. Unfortunately for me, I was told that all the intake valves were damaged, the likely cause being poor air filtration (will expand on this at a later stage). So all intake valves were replaced, and decided to swap some new camshafts in.
Head all freshened up and the new billet camshafts (intake & exhaust).
The lifter bores had to be heavily modified for the new camshafts.
Re-built bottom end and genuine Mazda head gasket. Deck was surfaced, bores re-honed, and new bearings/rings.
The valve train fitted and ready to be degreed.
Using the "Lift @ TDC" method, basically the amount of lift on the camshafts at TDC on the overlap stroke.
All degreed, but I'll go through the whole process again to double check. I did the measuring off cylinder no. 4 lobes at TDC, I'll do it again measuring off cylinder no. 1.
