Conversing with myself but here goes....
Spoke with AFR today.... he advised me the 227s will give me lots of room to grow, and I wont be using them to their full potential, however he insisted that even with my current set up those heads and that Intake will dramatically increase my power....
As for the shaft mounted rockers that the guy I bought the other stuff from was selling...... they are not correct for those heads. They are non-eliminator, and my heads are the eliminators....

I have the same heads but mine are the RACE ported versions, POPO's are the COMP ported. The COMP ported flow more. They have an additional pass made in the cnc process. They are as good as it gets.
I run Jesel shaft rockers, they were just over $1000 at summitracing.
I run aftermarket proform valve covers, and had to remove the baffles to get them to fit. The baffles were screwed into the underside so it took 2 minutes to modify them.
If you run shaft rockers, you cannot run head studs on the top row. I have an ARP head stud kit, but had to purchase a full set of GMPP head bolts and use the long bolts for the top row. The studs stuck up too far and interfered with the shaft assembly. The head bolts sat flush and gave enough clearance for the shaft assembly. When using ARP head studs, use the teflon tape to seal them and a dab of liquid sealant. It should have resistance when you are inserting the stud. If it goes in relatively easy, you didn't use enough sealant, and it will probably leak.
AFR sells a set of rockers with an offset pushrod cup for use on 227cc heads. The rockers are around $300 iirc. You would want to run a girdle as well if you are running a big cam. Girdles will run $200-$300. So you can spend around $600 for stud rockers/girdle or $1000 for shaft rockers, whichever is your choice.
When installing the heads I had to grind down the middle washer to fit it between the valve springs. I also had to trim the edges off of the nut that goes onto the stud for the same hole. If you google it, you will see it is a common step to install these heads. It took me 5 minutes with a grinder.
I run pacesetter 1 3/4 headers and was fearing that i'd need to step up to a 1 7/8ths header to work. Not true. The 1 3/4 headers match up very well to the exhaust port, so far no issues whatsoever.'94 coupe, 10.15 at 133.65 414" LT1, 4500 stall, n/a, pump gas, mufflers, street trim

Larry, did you ever find out what exactly was wrong with your car?

If you run shaft rockers you can sell the rocker studs and guideplates since they won't be used.
