Would swapping heads with later model (1986) improve performance any? It's been reccomended to me.

If your talking about a 86 stock type head from ford, no this won't help performance. You would lose compression and HP. The 1969 - 70 heads had the bigger valves and closed chambers
for more compression thus more HP. Unless your going with a after market head like edelbrook,keep what you have right now.

You're welcome Mike, glad it worked out for you. Roger, it's taken a few years but my inventory of excess parts has shrunk a fair bit from 1 1/2 garage stalls to about an eight by eight space. ...
