You can use them but will need a different head to bring the compression down.

Back in 1999 I purchased low compression pistons from Kanter's for my 1961 4 cylinder motor. Turns out they were the 10.25 to 1 pistons. http://www.kanter.com///productdetai...Cat=32&Prc=362
Make sure they are the low compression ones. Don

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
