I have a 1971 351 cleveland motor 2 bbl. and want to install a 4 bbl. intake out of a 1971 can i use the same heads or do i have to change them. I was told no
You can use a 4v intake but you wont get the performance unless you change the heads.I did this in the early 90s when i found a 71 351 cj intake in the junkyard.(still got the intake) in the trunk of a 73 z28 camaro.
