Default Head gasket thickness

Calculating the head to piston clearance on the 59L. I am using a Best Big Bore head gasket that is about .050 new. What should I expect it to be after 55#s of torque ? Also, does it make a difference which side of the gasket is up or down as long as the notch faces forward. I think I knew once but forgot. Thank you Fordbarners.

Re the notch and the up and down, if the notch always faces forward then one must be up and one must be down. You don't have a choice in the matter.

Best claims the gaskets to be .058" and the compressed thickness to be .055". Presuming you are using the Graphtite gaskets

So what head gasket do you guys recommend with stock heads on a 59A or older?

I still like the Best Gaskets stuff . . . the best They can be a bit of a pain to clean up after head removal, but they do work well.

I usually use a figure of about .050 for the compressed thickness. Are you sure you have an accurate mic?

I use thew copper gaskets like the 3036 and their 8ba counterparts, because I can reuse them several times. I also use head "BOLTS" because it's easier to remove the gasket with out damaging it..

I just checked the gaskets again and I get about .062 in the material area and about .067 in the metal fire ring. They are new, and I also realized they came from Speedway, and I have no idea who's gaskets they are. They look like Best gaskets, but ? Thanks you Mart for the orientation on the notch. So if a Best gasket starts out at .058, and ends up compressed @ .050, that gives me rough idea of what to exepct.

If they don't say 'Best' on them, then they're not. I bought a full-gasket set from Speedway about 2 years ago - and they were a bit tricky on their website, the wording made it seem like I was buying Best gaskets. They used a lot of the same lingo that Best uses - typical 'Speedway' when they're cloning something - not quite the same as the originals.

The 'clones' by Speedway were nowhere near the same quality as Best - the fire-rings were all goofy, the material was too thick, etc.. The timing cover gasket was .025 - .010 thicker than it should have been (screws up cam thrust). I sent the whole set back to Speedway and bought 'Best' gaskets -- they're named that for a reason! LOL

Here is what I sent them -- they were very nice, refunded my money, etc.. The lady said "nobody ever complained before" . . . maybe not, so I didn't mind being the first:

Here is the document I sent them:

Thank you Bored & Stroked. I will get Best Gaskets. That's the last thing I need at this point is gasket problem.
