I want to do something similar for my 68 Roar Runner. Only difference is that I will be using Edelbrock Performer heads I have on the shelf. [/quote]



I was going to go with Edelbrocks but the angle plugs would put the plug boots close to the manifolds. MP aluminum 452's are essentially straight plug Edelbrocks, but cost is ridiculous, like $2K+ for bare heads . [/quote]

I had zero issues running the Edelbrock Heads / Angled Plugs and Factory HP Exhaust Manifolds
