318 build #2 "cost minded" for the '74 Duster

Just FYI Chrysler Power magazine had an article about adapting the LA intake to magnum heads back in the 90's. They made some adapters out of some small tube/pipe stock, cut it to match the angle on the intake on one end, flat on the top, slotted the intake bolt holes, and used some longer bolts to put it all together.
Thanks! And now there are a few different avenues of using the LA bolt pattern, including using LA heads if one so chooses.
