A westy block is identical to a later motor, the only difference is the
head.  If you want to convert, you need to get a new head.  Honestly, for
most levels or road tune, there isn't a huge amount of difference and one
nice thing about the westy head is it is less thirsty with the fuel, and if
I recall there isn't much penalty on torque, most of the penalty is over
3,000 rpm, which for a road car really doesn't matter much.
