First, C8AE-H heads are common, run of the mill, garden variety...FE head used on everything that was not a 428CJ or 427. That includes all cars and trucks. The piston design determined the compression ratio.
The first part of your question is more opinion. You didn't provide any background on what your intentions are but roller rockers are a somewhat poor return on investment (regardless of what the seller is using to hype these rockers..."will pick that big block up around 20HP...") unless you're running a much stiffer (like over 140lbs seat pressure) valve spring and even then it's questionable. Those rockers in particular are bottom feeders. The bare minimum I would consider as adequate would have a bronze-bushed fulcrum. The top of the line use a roller fulcrum. If you look closely, you'll see that the fulcrum is parent aluminum. It is probably hard anodized or T6 treated but that's not enough in my book.
There are more and more valve train options available for the FE builder but the key remains in making smart choices. If you're not running anti-pumpup lifters (or solids) and reving over 6k rpm, then the factory hydraulic, non-adjustable rockers will work just fine. If you need adjustables, there are iron (Crane, FRP...) that will work with stock shafts and only need the ball and cup pushrods. There are some good aluminum roller tip and roller tip and fulcrum rockers out there. There are also upgraded shafts, stands, end stands, and spacers available. It gets real easy to spend over $1,000 on the valve train. If you're going to spend the money, you want to make sure that you get a return on your investment in either durability or horsepower (getting both is even better) and these particular rockers, again, in my opinion, are neither. |
