318 Port match heads to Performer RPM Intake

I started doing some 318 oval track motors in 92/93.
Some of the rules were stock heads with 1.88/1.50 valves, 10:1, stock iron 2bbl manifold.

The owner had lapped up the MP 302 head propaganda and had been running them the previous year.

I bought my first flow bench and started doing some testing.
I couldn’t see any reason why the 302’s would be better in a race application like what this was.
So, for the first trip to the dyno a head swap was going to take place.
302’s vs 596’s, both set up for 10:1cr, both had 1.88/1.50 valves.

The 596’s were about 40hp better.

That was the end of me messing with 302’s.

For something in the 300hp range, they’re probably fine........ but they aren’t something I’d spend a bunch of time on.
