well i have a few ways i might go with my combo

needing some opinions

combo
306 mexican block
stock length rod -h-beams
steel crank
weiand x-celerator intake
750 blowthrough carb
i would like to run a small hydraulic roller like the f-cam to keep it somewhat streetable
mp T70 -81 . or 96. still undecided on this too has 68 on it now
now questions

heads- i have twisted wedge heads 58cc
or 210cc heads they are the knockoffs look alot bigger runner wise and have not been milled
which ones should i use
twisted wedges have been milled so they might not have much more material left for blowing gaskets. will have to run a dished piston ?
210 heads well for one they are knockoffs not really sure how good they are but i still have them
they maybe a bit overkill for the combo with the t70 or is it just me thinking this

pistons- dished or flattops?


i am wanting this car to run mid to low 6s in the 1/8 and still be able to drive it on the street
probably 10-15 # on street and 20# at the track since i should not have block worries


thanks for any ones input on this in advance
if they are stupid questions than sorry
