305
One idea I was thinking about with my Pontiac was to make it true duals, and just have them stop about halfway under the car with no muffler or anything. I would think that would prevent burnt valves. I've never seen that happen before though, one of my dads Chev's had open headers all the time and it never once happened. As for loss of power, I really don't care at this point, the restrictive cat and single exhaust on it probably chokes it out more than just open headers would. lol.
I like 5-bolt, stronger than four.

I'm just disappointed that the Ford 5-bolt steelies don't have the same bolt pattern that my GM 5-bolt steelies do. They're both 15" rims. 👎 Otherwise I wouldn't have to bring my Pontiac to autoshop for that, would have had the good winters on it already at home. But now I have to switch rims and schtuff because of that.
