    I'm guessing this has been asked in the past, but hard for me to search due to just having a phone. I have 74 stage1 engine from a riv, it does have the stage heads. Question is, what oem intake from prior years can I use instead of the original smog type that came with it? I don't like the side runner tubes casted into the intake and would like a cleaner looking top end. I dont recall what years mate up with 74 porting. Thank you for any advice.
