[Roush #1]

Native,
On the other subject about the restrictive Windsor exhaust bolt pattern.....
My Roush heads (AFR 205) came with a dual bolt pattern that will easily accomodate a 1 7/8" tube and I think a 2'' tube as well. When I changed headers, I installed stainless studs for my header bolts and have a nut on them that requires a 9/16" wrench.
I can now tighten all the header bolts from the top side with a 10 inch long box end wrench.
I had trouble previously - when the bolts were in the narrow position - reaching all the bolts with a short 7/16" open end wrench.
Check out the dual bolt patterns by looking at the Fel-Pro #1487 header gasket.
Hope this helps!
Jody
