You can't use 4V intake on a 2V heads, but you can buy a 4V aftermarket manifold to fit 2V heads which works good.

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.

thanks
Pat
