L98 Corvette 350 swap question

55-86 sbc the intake manifold, all 12 were at an angle.
87-95 sbc the intake manifold, the 4 center intake manifold bolts went straight down and the other 8 were still at an angle.

I've seen some people take an 55-86 intake manifold and oblong the 4 center holes to work on the newer cylinder heads (87-95).

If the motor is a 1986 motor, then you should be able to reuse the intake manifold off your 1984 305.

Here's a pic with more info.
