Tom: sorry for the double post, thought I had edited it out.
I thought you might be in Fl. having a EM. I'm in Bradenton.
If your webers were jetted in the ballpark, all they should need is a cleaning & gaskets. Do you do your own mech. work ? Simple job x4.
Yea, the EFI's are in the ballpark you stated.
Not sure if the alum heads would be worth the effort for as little as you drive it.
Same with the alum FW.
