Pistons look different
i pulled one cylinder head today and noticed that my pistons have 4 grooves like for a 32 valve engine but i only have a 16 valve engine is this normal or may i not have the same engine as what came in the truck or just a result of rebuild

Re: Pistons look different
If they are all the same, donīt worry about it.
Mine are like that too.

Re: Pistons look different
No worries; this allows the piston to be used on either bank.

Re: Pistons look different
They can always be used on either bank. What the four reliefs do is allow them to be installed backward or forward without ruining a new rebuild which is handy for a lot of mechanics.
