Magnum intake drilling plate project
So started this project by borrowing a LA head core. Thank you Rick at Park's Engine Service, Seguin Tx.
Made a pattern with a fiber paper and ball peened hammer.
Did the same thing with a Magnum head. Here you go.
One problem I see already are the end bolts.
The brass pipe nipples will be installed into the steel plate I have. You bolt the ends up and that allows you to drill the center bolt holes. Then swap to the other plate and drill the last two.
