I'm aiming to place my 1984 350 SBC intake on my 1989 350 SBC engine.

The 89 engine was fuel injected and has the 4 center intake bolts are at a different angle. I'm looking for a better option on making the 28 degree wedges needed for making the flat bolt clamping surface.

My current plan is to work over a piece of hollow round stock (3/4" od 3/8" id) on the band saw at a 28-30 deg angle and the dress it by hand with a file.

The round stock pieces i have are 2" each and will require me to tack weld them to a piece of flat stock and then to clamp the flat stock in the band saw vice.
