Will Vortec heads fit a 327?
The L31 Vortec heads will bolt onto any Gen I small block. Your 327 isn’t any different than any other Gen I small block built from 1955 thru 2002. The main difference with using the Vortec heads is the different intake bolt pattern as already mentioned.
Are all SBC heads interchangeable?
All SBC gen I and Gen II heads will bolt onto the block. The LT1 and 4 heads are set up for reverse coolant flow(i.e. the water goes from the heads then through the block) so those aren’t what you want to use. The center bolt non-vortec heads(87-96) use a slightly different intake manifold.
How much horsepower does double hump heads add?

In a light to medium weight car, a 350 will probably offer you the happiest experience, especially in a daily driver role. In a truck, the 454 will probably feel better to your foot. In an all out performance car, the 454 will probably be more likable as long as the car is a straight line car (drag racing etc).

The Vortec heads are a little bit lighter than the older heads and have a “kidney” or “heart” shaped combustion chamber that is more efficient than the double hump chamber.
When did Chevy stop making the 327?
The last iteration of the 327 appeared in 1969 with a two-barrel carburetor and a 9-to-1 compression ratio that produced 235 horsepower and 325 foot pounds of torque, but by then another Chevrolet small-block had already appeared on the market and had begun stealing what thunder the 327 had left.

The difference in the displacement comes from the crankshaft stroke. The 327 uses a 3.25 inch stroke, where the 350 uses a longer 3.48 inch stroke(thats what makes it bigger). Depending on the year of the block, the biggest difference in the block itself is the main journal size.

Can you put 350 heads on a 327?
Bill, 350 heads will work on your 327. Avoid 305 heads like the plague, though. You will want to find some with similar size combustion chamber and valve size/port size in order to keep at least the same power output your 327 had when new.
