Been watching your thread!
It reminds me of the same thing me and my gearhead buds have talked about over and over.
When you decide to build a combo
you pick a power level
then pick a set of heads as a reference for rest of the combo
If we are talking about a stock short block NA combo here
I see three basic levels based on head choice
1) E7s
2) Ford oem gt40, gt40P, older 351 stuff, etc
3) Edel, TFS, AFR, etc
Lets say you got things matched really well to all three examples.
When you compare the performance between all three
The outcome is not that great between 1 & 2 or 2 & 3
Again we are talking about NA here and the only way to see a very big difference between the above is to compare combo 1 & combo 3.
Unless your budget is of no concern
When you only build from one step to the next, the gain for the buck spent is something you want to focus on cause it kinda makes you feel sickly
Having said all that, you can't disregard a power adder as an option to up the gain.
Then again ...... you just don't slap a power adder on without having to deal with issues it can bring just as a max power effort h/c/i combo can bring issues as well.
To answer InMyPrimeSVT's question ........................
A cam could make a difference, but not a huge one
A complete upgrade to the next level will make a difference as well .............
but not a huge one
See where I'm going here
Maybe a low level of boost or tiny shot of giggle gas
Decisions ......
Decisions ......
