Two. The standard Ford 302 and the 302 HO VIN M.

Isit because of the valve opening distance and the makeup of the cam shaft?
Yes, if it's a 302 and not a 4.6 like in the newer mustangs the 302 and all aftermarket 302 heads should fit.
There is no significant advantage other than less peak twisting stress over the entire length the crankshaft. The firing orders are 1-3-7-2-6-5-4-8 for the 351W and HO 302 motors vs. 1-5-4-2-6-3-7-8 for early 289 and 302 Windsor motors. Connecting rods 1 and 5, 2 and 6, 3 and 7, and 4 and 8 share the same crank journals. Looking at the firing order the early 289/302's fired 1 and 5 at the very front of the crank in order. This placed torque stresses from two cylinders in power stroke on the very front throw of the crank at the end furtherest away from the load of the crank. The later HO and 351W firing order places common power strokes further back in the crank, reducing peak twisting stresses over the length of the crank.
Very simply...it turns it into a 302 HO. It also changes the timing of the 302 to the timing of the 351.
302
The Ford 302 H.O. firing order is the same as a Ford 351 engine. It is 1-3-7-2-6-5-4-8. It is totally different from a standard Ford 302.
The 302 HO uses the same firing order as the 351 and is not the same as the standard 302. Ford 302 HO firing order is: 1-3-7-2-6-5-4-8 Distributor rotates counterclockwise.
Chevy built a 302 in the late sixties. It used a 327 block with a 283 crank.

My 1991 Ford Mustang LX 5.0 L ( 302 ) was rated at 225 horsepower
