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..
