Yep. You can also include the lifters and pushrods. When I had the MP
Magnum R/T cam installed, I decided to beef up everything at the same time.
The MP cam kit comes with a set of better than stock lifters (actually,
came with
10 of them) and the MP 1.6 aluminum roller rockers came with a set of
strengthened
pushrods. Generally, aftermarket rockers will have less spec. production
differences
among them than stock ones.
Lighter weight/stronger pistons are good but I stayed with the stock ones
because, at
that time, no one in the aftermarket had them out for the magnums. Custom
made ones were far too expensive.
