Are ARP head bolts really needed for a mild build?

I have reused the factory 340 main bolts 3 times now.

I buzz the motor up 7 grand.

The bolts are not going to break with the build you have.
the only bolts I ever up grade in 'stock stroke' street/strip motors are the rod bolts.

I only use main studs in stroked or above 7500 rpm motors.

I run the same kb243 pistons , use ported heads, solid cam, and have a 4 spd behind it.
