The pinched loaf tins gave me a good enough idea on changing the scale of the valve covers. I'm currently going over a bunch of my roadster inspiration pics and looking at the engines in more detail. While the simple even cuts that I made to the spare tin worked for a scale mockup, I think I see a better way to slice the main loafers to integrate better with the engine "block" and emulate not only the valve covers, but also partially emulate the valve heads. Also even though I like the curved exit of the top of the pipes, I think I am going to slice the valve head section of the tins to mesh with the upper section of the pipes so that the pipes appear to come out of the heads rather than the engine block. We'll see if what is working in my head works on the tins and such later. Thanks for the always welcome feedback, it keeps my mind and hands working through this fun stuff.
I think I am ready to work in some other medium than foil tape!!!
