You are right I am off on my exhaust valve being sunk reasoning because that would require a shorter pushrod. So in that instance I can't explain away the fact that the heights were inconsistent on one head. We did discuss this when I brought the motor in. I told them I want everything as close as possible, if new seats needed to be installed or extra time needed to be taken I was willing to pay for that. I explained that just because I have adjustable rockers doesn't mean that these heads wouldn't end up being sold to someone who would use the stock rocker shaft so I wanted everything as close as possible. Then I pick up the heads and brought them back to my shop and find that with a straight edge it's clearly visible how far off some of the valves are. When I called them to ask about it they said they didn't worry about it because I had adjustable rockers. Even though I specifically said forget that I have adjustable rockers I want the heads to work with a stock valve train too. I explained thoroughly to these guys that this motor wasn't a high mileage re-ring job. I was willing to pay the cash for a close tolerance quality machined block and set of heads. I explained this would be a high horsepower engine. They certainly charged me a labor intensive price that's for sure. There were things so obviously wrong with this motor my friend (engine builder who got me started on working with cars) said it was screwed up (he used harsher language than that) and that I better take it straight back and not even bother unloading it off the truck. The cylinder hone crosshatch had no angle to it. It was just swirls in the bore. The cam bearings were scratched up and the oil holes were in a different position for each bearing. The connecting rod caps on 2 rods looked like they were ground down with a dremel. The oil galley ports at the front of the motor that I went through the effort of threading and polishing out the old stake marks? They epoxied plugs in and then proceeded to make 8 stake marks on each plug. I gave them the brand new threaded oil galley plugs. I gave them new dowel pins, when I got the motor back none of them were used. They put the old pins on the deck, the intake dowel pins were missing. I'm sorry I could go on and on. The quality of work I received was unacceptable. I'm not an agressive guy or even an outspoken guy. It was extremely difficult for me to explain just how pissed I was to them. They charged me $2250 for an unassembled motor. I even had to spend $100 out of pocket to replace the can bearings they screwed up and they didn't even think they should take that off the bill. I brought my motor back twice to have them fix mistakes. This was supposed to be an assembled short block but when I picked it up and asked what happened they said they had no idea I wanted that. Even though they opened the box of rings I left them. I told them they will receive $2000 and not a penny more. They told me get the hell out and never come back. I'm sorry this isn't directed at you, I know you are a builder and a machinist and probably dislike to see people hurt another's reputation over misinformation and I agree. I'm not a machinist and I don't know all the ins and outs of what this takes. Precision engine services in Middletown, Ny is not a quality machine shop. I felt like giving up on this project and parting it out after dealing with them. I finally sucked it up and said I'm just going to check everything the best I can and move forward. The silver lining is I think I have found a good machine shop to work with and if I build another motor I'll definitely have him do the work, it's just upsetting I didn't know about him before. The guy had a TA V6 block sitting on a stand. He knew about the oiling modifications, the cam bearings. I mean it was enough to reassure me I didn't have to explain anything to him. Anyways sorry about all that. So my exhaust valve sunk theory is not right, which makes sense because these heads only had 40,000 miles on them when they came off my motor anyway. I see what you are saying on how the heads could vary so much between each other. I don't think it's a rocker mounting issue since all the intake valves are a different height from the exhaust on the left cylinder head. I will be checking ptv with a dial indicator and checking springs once I get the push rods and I'll check every cylinder. The deck had almost .070 taken off of it and the pistons are at 0 deck height so with the much higher lift cam I'm definitely worried about it. Cylinder #1 intake valve seemed okay as I put the pushrod tool in and rotated the motor over with no issue.
