I guess no one who is advocating for the b1bs is considering the application here.
My suspicion here is that the c body headers aren’t going to play that well with the raised exhaust ports.

Additionally, they’re really not that good ootb, and require quite a bit of porting to flow on par with for example....... ootb TF240’s.
And they’re not inexpensive to begin with, and require special rockers.

For the OP’s build....... they really aren’t the best option.
