Lt1 heads on 327?

Can I? Will they work? I saw a guy on craigslist selling a set of comple aluminium LT1 heads for 175. I was thinking of getting new heads, so my question is will they work. Right now I have a 1968 carborated 327 with missmatched heads. Figures 175 for aluminium heads not too bad if they will work

That was a cool thread. But way beyond my mechanical scope. I forgot about the reverse cooling. I just was reading about that today.

Yup
Intake ports don't match up to regular SBC intake
