"Fit" is a relative term. They will bolt onto the heads, but the ports will be partially covered.

Headers would be a much better way to go.

Re: lt1 manifolds in a 3rd gen

So if third gen manifolds are restrictive to the ports on an LT1, does that mean that LT1 manifolds would open the flow on my 92' 305?
