Thanks, I will look at some 1 7/8 also I will start price checking soon but I have to buy a set of slicks first. This motor has never ran what I thought it should and this will be the first year in a long time I will be running on the regular basis(I hope) so I thought about fixing the header problem. I would really like to get the car to run around 7.0 in the 1/8th current average is mid 7.30s. Zipper your cars weight is close to mine. Do you think there could be 3/10ths in the headers? That seems like a lot but I could be wrong.
