Over worried IMO, but not without merit.
Run the thick gasket and you’ll be fine.

Yes Sir I agree ! But, since how I don’t know what pistons the op has and I don’t know whether he has a zero deck , and there is a whole host of other things that are unknown I was just letting the op know that running a thick head gasket can give him more quench then desired ! You may have built this engine and know exactly what the op’s motor is I don’t know ! The facts are though if the op has to much quench or if anyone has to much quench , that can lead to a detonation problem ! Didn’t know if the op or anyone else knew that or not ! Since the op is not doing a motor rebuild just pulling the heads off , this could be some good info to know !No. But it would be advantageous to have the least amount of wasted
Negative Sir. Timing is more of the issue at hand, not quench. He could run a flat top zero deck piston with a .030 head gasket at .010 more bore size than the cylinder and a closed 63cc head while adding boost.
Now the amount of boost could be limited due to timing limitations. If the timing could be taylored correctly, he could still run 15 lbs. of boost.
At this point of running boost, I, myself, would run a forged slug.

These are the pistons

For some reason I cannot figure out what stroker kit I have. I’ve checked all receipts on my build and that’s the only part number I can’t find
Yes it doesn’t give you the deck height of the pistons ! You can put the piston on TDC when you pull your heads off , and measure the deck height then !

I doubt the bore size makes a difference on the piston head, but this from their website.
I didn’t see the pistons deck height ! It does give you the deck height of the block, but not the pistons that I seen !
Here is a for instance in this picture ! It gives you a Distance below Deck a plus or a minus figure !I didn’t see the pistons deck height ! It does give you the deck height of the block, but not the pistons that I seen !
Honorable mention head gasket may be the FelPro 540 PermaTorque SD. I’ve got a set and the bore measures 4.035 (Felpro says 4.065, but both of mine measure 4.035) and they’re .060 thick out of the pack, so by Felpro’s directions they should come in at .055 compressed thickness.
But you’re probably not going to drop much compression with the 11.5 cc gasket volume.

No, they're not an MLS and only to be used with DRY & CLEAN installation with a recommended surface finish of RA 60-80. If all the parameters are the same as I factored before you're going to be at 10:1 with them unless you have the chambers opened up.
here's what i seen that seems to work is 1008's torqued wait 12 hours retorque run engine thru 4 or 5 heat cycles retorque reset valves and damn near bullet proof at 10 psi with proper timing . jmso
The PermaTorque SD gaskets are made nearly identically to the high performance 1008 gaskets.
On a side note, some of the turbo ricer boys are using the .020 copper head shims (Felpro 8553SP in this case) with copper cote on both sides and high performance head gaskets without any problems at over 15 pounds of boost. A set with some Felpro 521 SD gaskets https://www.oreillyauto.com/detail/...1/automotive-truck-1985-dodge-d150-pickup-rwd would put you at 16.9cc’s, which should drop you to 9:1.
