Installing a Victor 383 - Q about bolts for cylinders 3 and 6

[shawge]

Installing a Victor 383 - all of the intake bolts go in just fine except 2 due to the bolt hitting the runner during install.

This is the bolt for cylinder 6 and cylinder 3 is the same. Bolt is an ARP 3/8" diam  1-11/16" length


Not sure how to move forward here. 

Do I use a grinder or rat tail file to enlarge the hole for the bolt?
Or do I use a shorter bolt?  A 1-1/4 bolt goes right in but the thread engagement is IMO marginal so something 1-3/16 to 1-1/2 range.
Or something else?

Thanks.

Install those bolts hand tight first while holding the intake up and away from the head to eliminate the crash followed by the others?

typical , I would use a shorter bolt if possible or grind a small relief into the wall of the runner

Thanks guys, after grinding a slight relief the bolt goes right in.  Now to finish the install
