i have two questions first i have some exhaust flanges so i can build a set of headers on my 40 merc flathead while i was bolting them on i noticed that the front bolt holes on both sides of the motor are 7/16 and the other holes are 3/8 is this right? and would it be a good thing to use stainless steel bolts?
Yes, the front bolts are 7/16. I wouldn't be afraid of either stainless steel bolts or just some anti-seize on them.
sounds good on the stainless bolts. so why did henry change the size of some of the bolts? thanks dreamcar.
I am useing stainless on my 8ba. Make certian they are not to long. They can do a lot damage if to long.
