Hi,

I have a set of +0.5mm pistons in my engine but they have 2 valve cut outs on each piston. Would they have come like this or would the previous owner have had this done. Its got a stage 3 head with a piper T2 cam & bigger valves as well if that makes any difference.

cheers, Duncan

 

Could be either dependant on Piston manufacturer

 

I'm not sure of the manufacturer but on the top they say AE +0.5 then some numbers !! does that mean anything ?

cheers, Duncan

 

Duncan I know that JE pistons can be ordered with pistons dished or valve cut outs!

HTH

 

standard RST pistons have very shallow cut outs on the tops anyway...
