Such as, how the valves are put in, other than maybe with the engine completely apart and you have to weasel them in through the cylinders heh I wonder if the "engine program that was abandoned" was the one GM worked on for a DHOC motor based on the SBC, before they found out it just wouldn't work and commissioned Lotus to design one (which became the LT5). There is no basis for me using "Concept Northstar", it was just the really small 4.0L that made me think of a NS motor heh

SUCH an odd duck!
