Several years back I purchased a '86 Oldsmobile Stocker. It came with a new engine, with complete shortblock - remainder to be assembled, but the heads had been passed by both Div 6 & 7 tech people and were freshly done by a known engine builder.
Well I was going to Texas to race, so I drove West and picked up the car and left it with friends at Denver. I did look at the heads (307 Olds 317's), and they were bogus in my opinion, so I decided to take one along to get checked. One of the well known tech people agreed to check it out so I took it to him and left. I came back an hour or so later and he said, "its good to go". So it passed. Then I pointed out the three things that were obviously incorrect to anyone familiar with that head. After looking at them again he said, "Yeah I wouldn't be putting them on your car if I were you".
So! What does "passed tech" really mean. Some tech guy who doesn't know squat looked at it and said it was OK? Remember, I had three (one very knowledgeable) look at mine and passed it. I had to show him the problem areas. Did Bill show him the changed valve angles he talked about? Has the lifter bore angle change been addressed with tech? The heads wouldn't need that odd-ball looking pushrod hole if everything was still at STOCK angles (exh. 3 degree, int. 9.5 & 4.25 degrees off center). Did tech even check that? Do they ever? Maybe they should.
So Bill, if you want to be, "legal to the T", as you said, maybe you should point out these grey areas to the tech people as I did and THEN see if they pass. If they do, then go for it, but Stock as a class will be ruined if it hasn't been already.

valve angles are within the 1* allowed, they are exactly what you have printed in bold above "stock" as ford machined them...as you should know... castings very from batch to batch, that's why it "looks" like they have been changed when in fact they have not, which is why I have said...these are the best set yet. The rules do say you are allowed to clearance the pushrod holes.
as far as the lifter angles..... I have gotten a dif answer as you have depending upon who you talk to. I have not crossed that bridge yet..
In honesty...I feel that if the razor blades for rings and gas ported spacer are legal, they are not spelled out as ya or ney in the book, but everybody uses them (the most expensive rings in all racing I might ad) I don't see what the problem would be with correcting the lifter angles as they are still .875 dia.
