First let me thank eveyone for their input. I have decided to use stock exhaust manifolds because of clearance and flow. If its good enough for that 350 it should work well with my 327. I understand it is a %40 flow increase over the old camel humps. It seems that OEM P/N's 12554973 RH and 12554974 LH but there is another that pops up. Sorry I dont have it available just at this moment. I may be nuking this out but is there a difference between the TBI and carb'd due to exhast tempature. I do not have to worry about the EGR so I will just plug the hole. My local U-Pull & Pay wants $30 each for the exhaust. I can find used on ebay for $45 + free shipping and I have even located new for around $45-$53 each. Shipping depends. So go with the new. But what I believe I need and hope to get from this board is where to get the information or can you provide the correct P/N's for these 906 heads. To be honest I'm starting to get lost with something as simple as this. Shorty headers are an option but is it worth it? I mean what am I gonna get maybe an extra 10 horses.
