I have 2 bare sets of Merlin Wedged Heads. Wedged, chambers and runners hand ported by JimV. These made 587HP on my 454's and they made 713HP on a 540. I only have 20 hours on them from when they were last freshened up.
1 of the 4 heads was cut more than the other 3 so I ran a thicker 0.059" head gasket under 1 head.
$800 for 1 set and $750 for the set that was cut to much.
Ferrea F2107 exhaust valves $50 extra
I can also have Jim load them if you want them complete

Any offers?
If separated I will cut 1 head to match the mismatched one so they will be a matching set.

jimmy valako does great work, mine were awesome.

Ditto on that

Thanks guys!
I am going to be running JimV's new Dart marine casted heads. Going to use my 454's for some R&D baseline. He is going to be putting on some 502's, 575SC's, 540's and I think 572's with Vortechs.
Just trying to lighten up the boat a little and offset some costs.

Bump

Ttt

Cool your in good hands, ask him to tell ya tthe story bout the shop up north and THE BRIDGEPORT machine good luck Brutha

What kind of intake are you supposed to run with those, oval or rectangle? What do the chambers CC at after the cut? Valve sizes?

Thanks!

You run a rectangle port intake. JimV welded up the floors of the intakes to match the ports of the heads, best of both worlds. The chambers of the 3 uncut heads is 122CC and the cut head is 118CC. So on my 454's I ran the MLS gasket to get the another 3.1cc under the odd head. Valves are 2.30"IN and 1.88"EX.

I have not removed the heads off the engine with the mismatched heads. I am only selling these to offset the cost of building the Dart heads. If I do not sell them I will just run them another season and build the Darts next winter.
Just trying to get some more scratch
