614 might be legit.

Is there any one who runs the 305/145/180 engine who can weigh in?

I just pulled a complete 305 core out of a 77 Malibu and it as fare as I can tell its never been apart,it has the 614 heads on it.I am pretty green and on a learning curve with all this stock eliminator stuff .I was looking at the 301/135/150 combo in a Firebird but have been talked out of it in favor of the 305
