I really want these heads on ebay, any opinions or advice.

One thing that I want to add, my car runs perfectly and I have no complaints about performance. My current heads are Merlin Rectangular Port.

Should I leave well enough alone and not mess with it?

Leave it alone???! Are you kidding?! These cars are built from the get-go to be played with. Go for it!
Oh, I have the same setup. You'll never go back to iron heads. But I paid $600 complete. 'Course that was in '74.

Thats the kind of push I wanted.

Thanks

These heads would certainly lighten the front end of my '88 Dually.

If you are useing the car on the street you would be better off with a good set of oval port for low end grunt.

Those heads are going to fetch a ton. You would save money by getting AFR Brodix or Dart heads.

Yeah, you are the second that suggested that. Actually Dart or World is what I was also told.

I am kinda liking the Merlin III's.

Thanks

They are actually a pretty good street head (290cc intake stock) and weren't stock on anything so they really shouldn't be worth alot.
