I have gone for a Kent 34 complete kit with springs lifters etc, I had the sump off over the Christmas break and checked everything the shells all look good but the oil pump pick up had sucked up a lot of crud/bits of cam. I've ran the cam in as per Kent's instructions which was fun running a rst at over 2500 rpm stationary for 20 minutes! got a little hot but not too bad. The engine sounds a lot happier now, albeit still a little bit chattery from the lifters but 99% better than it was, its also comes on boost a lot quicker which is good! the oil pressure is also much better, 15-20psi hot idle but a massive difference under load, 3000 rpm is 45-50psi as opposed to about 30psi before! just the brakes to do now as they are terrible!
