You redrilled the intake to now use vertical bolts? & I am assuming some spacers sliced at an angle on one end to go on the bolt(s) first (so the angle matches the angle on the mani where you drilled). First confirm what size of port openings you have (head & intake) as there are (2) sizes of SB LA intake gasket port sizes that I am aware of: felpro numbers, one for a 318 & the other for a 360. I can find them later.
