I need some help finding some head gaskets, I tried looking at cometic's website but they don't have the size I need. Anyone know a good website that has a pretty good list or do I need to get them custom made? I need to get something like a 4.060 bore and .060 compressed thickness.

Anything above stock thickness(.052) is probably going to be custom made. Your best bet is to call Cometic and see if they can help.............

I was hoping that wasn't true...but I have to have a thicker head gasket because the heads were milled so much. Thanks though

I think Thunder Racing have thicker gaskets:

Well I have a 4.030 bore, so I think a 4.060 is what I need.
I was using the DCR calculator and am a little confused. I enterd my motor specs like this

Bore 4.03
ST = Stroke 4.0
RL = Rod Length 6.125
Number of cylinders 8
Deck Height -0.008
Piston Dome or Dish (- for a dome + for a dish) 2 (do I enter 2 for -2cc's or should I calculate the cc's into inches, which would be .006=1cc?)

Compressed Head gasket thickness 0.06
Cylinder Head Chamber Volume 61

with a cam at 113 lsa my compressions specs are this:


Static Compression Ratio 12.31871151
Dynamic Compresion Ratio 8.698853325

But if I put the -2cc's for the valve reliefs I have on my piston in inches I get:

Static Compression Ratio 12.63174944
Dynamic Compresion Ratio 8.911778011


So now I'm just confused to what gasket thickness I should run?
