1 5/8 vs 1 3/4 Header ????

[tonyvlx]

For my Novi blown 306 roughly making 450-500rwhp. What would you guys recommed? 1 5/8 Longtube headers or spend the extra $$$ and go for the 1 3/4 longtube headers.

THANKS

For your HP requirements the 1 5/8 will be plenty big enough to flow what you need. It will most likely give you more torque as well.

What ever you decide on make sure they have good collectors on them. Thats where you will really see the difference in power.

definatly 1-3/4" for that combo.
