Fresh from machine shop. Were blasted, magged, milled .010 to assure straight. All new stainless 2.08/1.74 backcut valves, new comp double springs 130# seat pressure good for .550 lift. new bronze guides, all springs shimmed to proper installation height, all valve tips leveled. No port work, just gasket matched. had these done for a 440 I was building. Over $500 in work. $350 owns them. Bolt and go...... Should support 500 HP. or for $500 get the fresh .030 over 440 block, resized rods w/ ARP bolts, and the std/std polished crank. Have over $1000 invested in the works
 

Yes on bronze guides, new seats as well. 3 angle valve job, hand lapped. Not ported, just gasket matched. pics to come. Very nicely done set of heads. all springs were shimmed to proper installation height. all valve tips leveled. Not just thrown together. been sprayed down with cosmoline so they dont rust
