The guy sad he didn't like headers (why ) suggested Vortec manifolds)and if I wind up building the 350 I have I'll be using Vortec heads and the manifolds they put on them. I strongly doubt there are interference issues, his are logs above the spark plugs, Vortec manifolds run along under the spark plugs. IMO this would be more desirable for the wires running to them. The vortec manifolds also have heat shields so that helps the boots on the plugs. At my local pull a part, exhaust manifolds are 25 bucks a piece, headers are going to cost twice that to start and if he wants good ones we're looking at 150, not including the extra modification to the exhaust system for headers over the manifolds even if they needed to be modified for them.
Looking at the pics of Vortec manifolds and looking at his the exits are about in the same place and angle, they should work and will be 2-3 times cheaper than headers but he said he doesn't care for them. I'm giving a cheap suggestion that should suffice for his needs. If he wants and can't find any locally, I'll pull a set for him. I'll only ask he pay what I paid for them plus the cost of shipping without a thin dime for my time. I know what it feels like to turn wrenches on a budget and I think I need to go to the yard anyway so it's no big deal to me.
