The line I am using is 8AN aluminum tubing from Summit. When I do my heater lines I am going to use 10AN line. 8AN is 1/2 10AN is 5/8. I used regular AN fittings 37 deg flare. You use tube nuts and tube sleeves it isn't very expensive. I have all the bolts most all of the bolts on the engine I replaced. The only reason I have only two bolts on the manifolds is because I was mocking them up. They will be removed and ceramic coated jet black. Thanks. I am happy to answer anymore questions. I still have this piston coating if anyone is interested.
