Fel pro one piece oil pan gasket

[moreHP]

Has anyone used the one piece oil pan gasket for a small block chevy? My engine is the late model with the one piece rear seal and the gasket kit from felpro has the one piece oil pan gasket.

My question is that it seems a bit thick on the front and rear seals where it goes over the timing cover and rear gasket housing. Just setting the pan on there and its a good 1/8 off the rails of the block. By putting the four corner bolts in and tightening them up, I can get the gap to close but I am not sure it is right and am a bit worried about getting it to seal. The gasket has the little steel sleeves around the bolt holes to keep you from over tightening it but it will take more than the 8-10 ft lbs of torque I usually use on the bolts to get it to sit down.

Any thoughts or input from anyone who has used these gaskets would be appreciated. I looked around for instructions on the felpro website but there was not any good info.
