I have a bare set 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.

Manley intake and Ferrea exhaust valves also available.
I can also have Jim load them if you want them complete

How much is the comb chambber volume ?

Does it is alluminum head ?

Also do you think that it can fit on a merc 525sc ?


Thanks

approximately 122cc, steel not aluminum, and yes they will work on a 525sc. They would probably lower your boost, and build more horsepower compared to a stock GM rectangle port.
