I looked into those Venolia pistons. They come without wrist pins. Sourcing w=
rist pins alone is an issue, and they need to be matched to the piston. Just=
 a heads up=E2=80=A6

The way you propose to use the car, the flat top County Pistons and matched l=
iners available from most suppliers will do fine. You will need to shave the=
 head just to maintain your stock effective compression ratio due to the lat=
e closing of the intake valve with that cam. Take .100 off the head, clean u=
p the combustion chambers and enjoy.
