Rings wont fit.

Hi I have a 89 5.0 that I am rebuilding, It is a re ring job- the cylinders did not require a bore, Just a hone.

Today i was putting in the crank, new bearings .010, and new rod bearings and ARP rod bolts on the stock 302 SRP slugs when I went to install new rings....

I went to put in the compression rings and they were to fat. They look just a hair to thick to fit. Same with the oil rings. They are sealed power rings.

I thought maybe I got a wrong box. I Picked up a set of rings chromoly rings, again made by Sealed power, and same problem. I have not really put a good force on the piston ring compressor, I shouldnt have too to get them to fit right??

Anyone had similar experinces??

I dont want to reef on the piston ring compressor tool, The rings should slip right into the groves correct?

thanks for the replys.

You guys were right.... I ordered the other set and they fit like a glove.

One question... For the compression rings, half of the compression rings have a somewhat shiney silver face(side that will touch the cylinder wall), the other half has a dull finish that is the same colour as the ring its self.
Does it matter which one goes up top? Both rings have have the dots to show which side is up or down.
E-458K was the ones that fit.
