My 55 engine has that aftermarket oil line in place under the side cover adjacent to the pushrods. Both of my heads, the one on the 55 engine and the one on the 59 are 848 heads. Both engines had high oil pressure. I guess I need to determine if the engine block is drilled for oil to flow to hydraulic lifters. I bought this engine from a fellow bolter and it was probably rebuilt at some point but I don't know if it was originally an engine with Hydraulic lifters. What and where do I look to determine this detail ?
