Well........the gasket you listed holds 3.2 cc's
a standard FPP 1094 which is .041 thick holds 9.1 cc's

SO you would be like milling almost 6 cc's from your heads ... just by going to the thin gasket ... ( or your heads being 70 cc's )

.

 

if your engine is togther it want be worth the hassle, my 2 cents

 

if you are going to the trouble of chaing head gaskets why don't you just cut your heads and end up with what ever c.r. you want.you can use gaskets for smaller engines to help lower c.r. but it won't get you as much.i have a 406 and sometimes use a 350 gasket because of the dia. of thegasket cylinders.a good hypereutectic will only cost you 170-180.00 and a cheap set about 60.00 less if you go to ebay stores.

 

Use a GM head gasket. I think its about .025 thick.

Go here then do a search for head gasket.

 

Well dont have enuff money for new heads or even milling them plus their 882's so their thin castings and I dont think those are recomended for cutting. Hassle? How's it a hassle? heads have to come off anyways - make sure everythings ok under their, and its old old gaskets on their...this is a major major backyard budget build and I thought spends $40 or so to raise the compression a little bit would be worth it...

Also what about the bore size? 4.100 is that just how all gaskets are...seems like the .100 more would be more prone to blowin it or somthing couse it is exact 4.000in bore, wouldnt I want want that fits even closer to the bore?. idk just a thoguht

But anyhow...would that gasket work? says its "Use in some Sportsman drag race and flat top Oval Track catagories. Cannot use on aluminum block with liners." - is that still ok for street

The steel shim gaskets work fine, you can get them at any auto parts store. Installing the thinner gasket helps in two ways, increased compression and reduced squish clearance.

 

Would I even notice a power increase with the thin gasket? .5 compression increase?

It's a move in the right direction, and you can't argue with the cost. I believe you will notice a slight improvement in performance and efficiency.

Be sure you get the heads checked for flatness on the bottom. Those shim gaskets won't seal if the head isn't almost perfectly flat. You may have to have them milled anyway.

 

How much deck clearance do you have? At least .020"?
I wouldn't go with much less than .035 piston to head clearance. You don't want the piston to contact the head because of thermal expansion.
You should recheck valve to piston clearance too.
