Those heads only came on "truck" motors, right? Could not build a traditional stocker motor because they never came in a passenger car, correct?

i/SA 65 Impala in progress. 396/935 "Oval Port"

There is some passenger car combinations legal with these heads. The cam is 228/238 @ .050, very mild, I did run it to 6400 RPM on the dyno, my peak power was around 6100 RPM.

I've been told a 1975 Chevelle is legal, not sure it came that way though.

73-75 are allowed the 236 peanut, 90 454ss truck uses the 360 peanut, 91-92 uses the 148, even smaller peanut port. Seems to be plenty of SS/GT 454's using the 236.

I remember hearing that Lingenfelter ran a killer peanut port combination in SS back in the day.

I know very little about factory stuff, and less about big block factory stuff. I have an engine on the stand in the shop out of an 80's 3/4 ton truck that will eventually find a home in my wife's 55' F100 (don't start....i know). Just a street truck. How do you identify the factory heads? What's good and what is worthless?
