Passenger side accessories bolt hole size on AFR heads help
So I used the bolts from the stock cast iron heads for accessories bracket on the driver side with my AFR heads and they fit great but the passenger side AFR heads bolt holes or smaller or have a diff thread pitch. I can get the bolt to start maybe one thread befor it stops....what bolt size do the AFR heads take on the passenger side?

The threads might not be cut right. Might want to run a bottom tap thru there and see if they clean up.

All SBC gen 1 heads, stock, aftermarket, afr, brodix, dart, etc.... Uses ONLY 3/8-16 for acc. bolt holes in ends of heads and for exhaust manifold/header bolt holes.
