I have got Manley Hbeam rods, Mahle 4032 pistons,king main and rod bearings, arp main studs. Hoping that the machine shop will have some good advice for me!! The chip is very small on the bottom of the bore. Not in the ring land at all, just on the fence on what decision I have to make.

I was not sure if I had to loosen the cam sprocket and the Vvt while putting on the new chain. But I did order new washers just in case. My plan was to replace the tensioner and chain, not touching the cam sprockets. The guides look good same as the oil pump Sprocket and chain. do I need to...
