1965 Barracuda 273 rebuild...intake code?

Last spring I installed a 318 Edelbrock spreadbore manifold, that I bought on this forum, on my stock 273. I had no problem with the different bolt size. The bolt holes lined up. I made wedged washers to adjust the angle of the manifold. I also installed a higher lift Comp hydralic cam. I had some problems with push rod sizes but once I had Manton make custom push rods, everthing went fine. I wish had stayed with solid lifters because of the problems. I was concered about the mismatched passages so I called Edelbrock. They told me not to worry about it because it helps keep the air velocity up and helps with throttle response. In racing applications, it’s common to port-match the manifold to match the cylinder head port entry or opening, for peak performance. In street applications, the only time port matching your intake manifold to the cylinder heads is recommended is if your operating range exceeds the manifolds range, or on large displacement engine combos. The engine runs great!
