Trick Flow small block heads

I have a question for you all and need opinions ......... I have a 273 commando that has a nice build on it and will run mid 13's now . How would these trickflows react on a little stouter build? like with a bigger solid cam like a erson 286-510lift like the d-dart had , better intake , larger carb , 1/3/4 headers ? stock bore in it now ! so i would need to notch cyl bores for the 2.02 valve heads. going to build a stroker 416 with the tf's in near future..

Your not gonna find to much on 273, I'd look up 4.8l LS, 4.6l and even 289 builds see what cams heads etc.. and how it effects the rpm powerband.
