Looking for more opinions/results, etc with the standard head, no offset lifters or exotic shaft rockers, and if you used untouched heads or the CNC'd ones, which did you choose, what chamber cc did you use, and at what compression ratio did you end up with. The big question is did they meet your expectations, or were you disappointed.
If its easier to just PM me to limit any BS, that fine.

I believe the issue people are having with their 400+ cfm KRE ported heads is those have very tall ports and guys have trouble getting Victors to work without welding. Its a tall port to start out with. There are sets of those heads that seem to come up for sale as a "great deal". Reasons for that.
That said, this summer I will have a std port HP 461 firing up. Port openings are near stock with bowl opened up and blended 2.20 valves go 359cfm at .800. Still .350cfm where I can use it in the .700s
My heads I had sent bare to SD Performance so they did the seats and guides and the rest. 80 cc, 10.80 CR right now but will mill off a bit to get to 11.20 or so.
Victor has had plenum work, just sent 1050 carb down to get worked, 16 hole billet annular boosters installed.
A few bells and whistles, big kick out pan, V pump, ported rings with crank trigger and a sweet custom roller so I expect a good result.
I will start off with a 850 without the crank trigger and work 1050 and crank trigger in. I expect to get in the 9s and I do not want to do it right off the bat.
I will let folks know how it runs. But not dynoing this engine. Where I live its a major trip, expense and pain in the A. Drag strip and scales will be my dyno.
But you know, there are some nice std port 340-350cfm CNC programs out
there. People love the new E head with CNC chamber. And you do not have to worry about hood clearance issues with E heads like a High Port.
