I could use some help finding correct headers for 68 Camaro with small block and aluminum heads. I have a set for straight plug heads and #3 plug on my new angle plug heads hits headers. Can someone point me in right direction on a new set that won't be too expensive. My car has 383 with patriot performance heads, ps, pb, & vintage air with billit specialties front accessories package. I was a little overwhelmed with amount of choices & part numbers available. I know someone on here has ran into this problem. Thanks for feedback.
