3.0sc case, when upgrading to 3.2 cyls/pistons, can i use my 79sc3.0 heads in stock form or is modifacation manditory ,once again thanks for all the info

Stock heads are fine.

When you say upgrading to 3.2 cyls/pistons, are you saying you're getting a set of 98mm pistons and 98mm cyls? Or are you saying you're switching to 3.2 Carrera pistons & cyls? If 3.2 Carrera, that's not a 3.2 when you are using the SC crank.

Carrera is a 3.2 because it has a longer stroke crank. SC and Carrera share the same piston & cyl size- 95mm. Can't use Carrera pistons w/out using modified (longer) rods. Well, you can (I have an engine that came to me that way) but it's way down on compression.
