What engine and car they were designed to fit.
block hugger headers
No.
yes
No.
no
The headers would be the same anyway, so you can order headers for the 83 and be all set.
No. The Pontiac headers will not bolt up to the Chevy small block.
Don't buy slip fit headers. If you are going to spend the money, spend it right. Slip fit will give you a big headache, no matter who installs them. They will leak like a sive and drive you crazy. I recommend that you get hooker headers.
Yes if its stock no headers?
yes
YES. They will bolt right up.
Not even close...
