What about a set of 920 heads ported with 360 1.88" and 1.60" valves??? Those should match up well to the ported 302's...

I'm building a 318 with a set of those....

Here is some real data, theory and track time. See post #47. The 273 heads were 1966 castings, with 1.78 intakes and 1.50 exhaust valves. The 66 273 heads are flowing just shy of small valve "J" heads. Pretty interesting... 302 heads
