    Fine work good looking but bad run lowest Idle. There are strange sounds while running I found a mistake of the timing because the camshaft hast wrong angles one one of the cams. Input valve open too late and it suck Vacuum short time while intake. So ist has bad sounds in idle. Here It on video..... I Change the camshaft Made out of MS from another Engine and it runs and sounds much better.
