New Small Block Headers

hoping they make a good bit more power on my motor than what the 1 5/8 Dougs coming off did.
I considered just buying the 1 7/8 TTI’s, but I thought these should Make more power, and fit even better( not even considering they are stainless to boot)
I talked to Nick for a good bit about my combo.
the estimate he threw out there was identical to the thoughts I had.
time will tell. Unfortunately, making couple other small tweeks, so gonna be an educated guess as to exactly what the headers did.
