I have EQ heads. They were just gone though. No complaints from him except the excess casting sand was a pain to get out on final wash. My only other complaints is spring pockets were not the size they were supposed to be. No big deal as they were machined also. We resized the guides, blended bowls, backcut intakes and new valve job. No complaints about the castings or how things line up.

Lol that's funny. There aren't many shops that check to see if Rocker stud is is parallel with valve guide. It's easy to center Rocker tip on stem and and get the sweep in the center. The Rocker tip has to be square with valve tip. My heads needed machining right out if the box. I took engine out for high oil pressure. After inspecting upper valve train I saw problems. Those heads are supposed to be ready to assemble. By 5he time you spend all that cash straightening them out you could easily buy cnc ported dart, afr, ect. Assemblies ready to bolt on. Stop giving people hope. I bought 4 of these poorly machined heads. Every single valve was off right out of 5he box. I had all seats recut before assembly The other engine will be be pulled at end of season to have those heads fixed also. IF EQ WANTS PART OF THE ACTION THEY NEED TO STEP UP THERE QUALITY, WARRANTY AGAINST MANUFACTURING DEFECTS AND COSTUMER SERVICE. PERIOD!!!. I'm not talking spring pockets. Take them out of the box and you can see light between the seat and valve. REDICULOUS. Tolerances at my Plant is like 6 microns. GM POWERTRAIN.
When you say you had the seats "recut" , was this before they were installed ? You earlier said the seats had to be REPLACED, was that before or after?
The 1200 dollars spent on them, was that soley in machine work?
The few friends I have that have purchased and used these heads, I strongly suggested getting them checked out and assembled by a professional cylinder head shop. Actually that goes for any brand head. There have been plenty of issues with out of the box name brand heads as well. Its no different than assembling a bottom end. You cant just order up a block from dart, and just hope the clearances/tolerances are good to go. Even a brand new dart/merlin block needs a bunch of machine work before its ready for assembly.
As far as cost, last time i looked, a pair of Dart CNC 335 MARINE heads, with inconel valves , anodizing, and assembled, was just under $5,000 a pair. And even then, i would still want to check them out before bolting them on.

Ok, sounds like a thread that was heading into the mosh pit just calmed down. Veloc410 just deleted 3 threads. Endeavor and SB both have quotes os the first one posted. Mild Thunder and ICDED both have quotes of later posts. He can't delete you guys quotes of his deleted posts. Only you 4 can. And I will edit this out and replace it with a stupid question after this is taken care of.
