even with the better block i am not interested in more rpm.[6800] 
What if you stepped up to the B1 heads, instead of those smaller B1BS heads? You might have to get another manifold, tho.
i dont want to have to switch valvetrain,pushrods...to port match my intake to the bigger b1's may not be easy.my HP goal is small also so i only need a little better heads.a lot to think about.
i know dave weber pritty well.he did my block o-ring and ballance work.this was before i knew koffels.

I run 440-1's, 345 cnc'd 2.25 intake valve out of the box from indy, 23lbs of boost. If i would have built this from the begining my way it would have had a 4" crank in it.
Right now I am leaving the starting line with 4* of timing and ramping the timing in over the next 2.5 seconds. I shift at 6800 and go thru around 7200. I run a 29.5/10.5 tire.

Is 23 lbs of procharger boost the same as 23 lbs of roots boost??I am still limited to 5 lbs of boost  ,,,,,,,,for now  
HEMI-ITIS has no cure.
