    2.2 Mahle

    I have a n. o s. set of 2.2 PC`s I`ll be making my 2.0 to 2.2 spec. I do not have the 2.2 heads. What is the best alternative to use wanting to make about 200 HP....or is sticking with 2.2 heads the best...Thanks,Cliff

    I'm afraid using 2.2 pistons with 2.0 heads will result in seriously low C.R. like about 7 1/2 to 1 with S pistons. You would be using a shallow dome piston against a head made for a large dome piston. You need to change heads to 2.2 or 2.4.

    Those will be fine, the valve sizes were all the same T,E,and S, you can size the ports however you want, and the bore size is the same so the 2.2 cylinders will fit.
