Yet another bloody header question

I have an 86 silverado which is about to get the 305 removed and a gm crate 330hp HO put in its place.Can I use the original manifolds on the vortec heads until my bank account recovers?
If not what headers will fit .It is at stock ride height.

Re: Yet another bloody header question

I think the ports are the same. So you can use your manifolds.

Re: Yet another bloody header question

hi thought i'd mention
i've ground down the bumps ,and smoothed out just inside the manifolds
i found it made a difference in flow and noise for sure
......for about $20.
