Headers or Ram Horns for 350 tbi conversion?

[68isgreat]

I'm doing a 1990 5.7 tbi/ 700R4 conversion in my frame off 68 C10. It was a 6 cyl/4sp. The engine has about 90k on it, out of a suburban. So far so good, have most of the swap done except harness and headers. I only have about 4" clearance on the drivers side between motor and frame, so I'm wondering if I should just go with ram horns? Or are there long tube headers that have hugger clearance, and don't cost $500? I would consider notching the frame too, if it's not too much.
Curious what you all recommend. I put new support and mounts on the front frame hole. Thanks.
