Agreed..049 or 781's will get you there. I'm running the 781's, 10.4:1 comp. small solid cam with stock stroke and am making right at 600hp. Should eb good enough for a mid 10 sec pass

Also agree that if your machinist is trying to sell you something you don't need then you should find another guy
You can make good power with the 049 or 781 heads. I ran the the 781 heads. I did a bowl blend, gasket match and 2.19/1.88 valves on mine. I think the 049 heads will easily meet your goals, IMHO.

No it is not like that. He has been building me and my dad's race motors for years at very good prices. I know he isn't trying to get more money out of me he wasn't trying to sell me heads, he was just going to call a guy that he knew kept some cores and have me go buy them from that guy. I am not sure why he thought those heads wouldn't meet my power goals though... Either way I am spending the same money with him to rebuild the heads. But I do appreciate everyones help and opinions here and I will use the 049's.80superbu said:
As for the rods do you think I should go aftermarket on them? If so which rods should I use? Also what pistons should I go with? Robert, You mention getting a cam for E85 specifically, do you have one in mind that would be good for me?
I appreciate everyones advice and opinions, keep it coming guys.
I agree, there isn't a better GM oval port head made. When World made their Merlin Oval port head, it was modeled after the 049/781 head. What core is going to flow better? I can completely understand if he wanted you to go aluminum due to the fact that cost of machine work on the steel heads may get you close to an aluminum. That is being honest and good business. Telling you those heads won't work isn't.
I google 049's tonight and found out lots of good information about the heads, I am definitely using those heads.
There are a lot of US made pistons. Getting a set that match your goal the performance level.
Rods, it's hard to spend money on the stockers to upgrade bolts and bushings........
And a US built set will be in the $1K area.
Maybe I missed it. What kind of cam?
Solid or Hyd flat?
Roller?

Auto or Stick? Stall if Auto?
Hyd Flat, Well, ok.... I'd get a custom to get the lobes placed correctly. There are cheap enough.
There are not many off the shelf cams that really work well.
**Edit Spelling**
auto. 400 turbo with "switch" or "variable" stall convertor, pump, and input shaft. 3000 stall on high and 2500 stall on low.
