The one-piece Fel-Pro gasket is more likely to be leak-free, but you'll see the blue edge of it all the way around the pan. The stock 4-piece gaskets can also be leak-free with careful installation and attention to making sure the flange on the pan is dead flat, especially at the bolt holes. Your call.  :)

Won't the blue edge not be visiblle after you paint the engine? Will this pass for judging?

Paint doesn't stick to silicone very well.

My 302 pan is leak free using the felpro one piece, the paint doen't stick to well but I'll trade a little blue, for a leak free install.

Make sure you get the right gasket for your oil pan; if your pan is the original, it takes the OS-34509-T gasket, with the "thin" (0.22") front seal. If it's a Service replacement pan manufactured after 1975, it takes the OS-34510-T gasket with the "thick" (0.41") front seal. If you have the later pan and use the earlier gasket, you'll have an oil leak you won't believe.

If you're not sure which pan you have, flip it upside-down on a flat surface (without a gasket) and measure the radius of the front seal opening from the center of the opening down to the bench top. If it measures 2-1/4", it takes the original "thin" front seal gasket (34509); if it measures 2-3/8", it takes the later "thick" front seal gasket (34510).

It is all about the front of the oil pan radius dimensions. The post above with the measurements of your actual pan is what you need to use to determine the right gasket.

9 thin and 10 thick, but I have seen some reference to left or right oil tube? In one description it described the dipstick as right side thick front for the 34510. Mine and most I've seen are on the left or driver side and thick front gasket?

The correct gasket looks like this.

Much later production engine blocks (maybe 1980's?) can have dipsticks on the passenger side. The small block v8's used during '67-'69 in Camaros would have driver's side dipsticks. Anyone could put a later model block in during an engine swap I suppose.

I see in the picture that the gasket comes with hardware.  Does this mean that the gasket is thicker and requires new hardware?
I was going to order this gasket, but I want to be able to use my original hardware.  Can the original hardware be used with this gasket?

Jeff;
 I used my original hardware no problem. I don't remember my gasket coming with hardware?

Both gaskets (34509T and 34510T) come with all new bolts and plastic pan hold-ups; the 34509 has only the left side dipstick hole, as all pre-'75 engines had the "thin" front seal and the dipstick on the left side. The 34510T with the "thick" front seal accommodates both the left-side or right-side dipstick.
