hello all I recently purchased a 2006 vw jetta tdi from the junk yard. it had a valve drop in the #2 cylinder due to worn cam / lifters had holes in a few of them w/ a piece of the valve sticking out of the head. surprisingly the cylinder wall only had two slight nicks in it so I got a new / used piston and rod, and a new / used head w/ cam and valves that fit right on my block. there is one difference. the openings on the head for the intake are the split type openings (vertical piece of metal in each opening) my original head doesn't have these and my intake manifold isn't a split opening. I know I am close to top dead center because I had cylinders 1 & 4 up when putting the head on, and the head was at top dead center. I cranked the engine by hand probably fourteen times and never felt any resistance of valve / piston contact I am waiting on the timing tool to be shipped now because I tried to start it and it cranked fine w/ no noticeable clicking but wouldn't start. is the head / cam compatible with my block? any info would be appreciated thanks.
