Returned to do a little more on the assembly and first thing I find is the crank sensor design changed at some point and the brand new one for an ‘89 is totally incorrect for the ‘95 damper, photo below. Investigating via Rock Auto, it appears the design changed for the ‘93 model year. I thought it might be peculiar to the S/C variants but that turned out not to be true. There were S/C engines beginning in ‘91 but the crank sensor was the same as the LN3 up through ‘92. The late model is larger physically, one piece plastic, non adjustable and the sensor spacing is much wider. It does use the same mounting pattern as all others. I tried to get a photo of the timing chain damper to show how close it runs to the back of the oil pump. Not the best but hard to see when assembled through the bottom of the front cover. Photo of the ‘95 heads with just a little wire brushing in the chamber and ports. They don’t look appreciably different than any other prior to the Series II. The exhaust seats look pretty wide, which is pretty normal for a Buick but these look wider than normal. Hopefully they are usable without a bunch of rework.
