Are you sure about that crank stroke? That's kinda strange. It will give a -.047" deck clearance and figuring 68cc on the heads 9.2 compression. Nice parts and it'll certainly work......most people shoot for closer to zero deck height. Was there a reason for this particular combination?

I ask because I have a friend who might have interest.

8 bolt sb crank?

I check my engine math at doverusa.com an a bore of 4.070 5cc for piston head gasket of .018 steel oem deck of .025 and a stroke of 3.510 the engine is 10.08 to 1

 

[css426truck]

That aint right. Go to the United Engine site and plug in the following in the deck clearance calculator.

deck height- 9.6

rod length -6.123

compression height- 1.675

stroke- 3.51

You will come up with .047 in the hole. Unless that block has been decked, that's what you will have. That's why I asked.

Now, I ran the compression calculator with the generic .038" head gasket, so your thin gasket would add some there, but somehow, you got the deck height wrong.......unless the block has been decked and you know that specific number.

Went back and ran the compression figures with your .018 head gasket and got 9.6. I used 68cc's for the heads.....another unknown, but good guess. And for the gasket bore I used 4.1 which is pretty popular.

Just curious, where are you getting .018" thick head gaskets? I think a lot of guys would want those.

OK think out side the box! Mill the block .020 a good engine build can help you with this and look for nos steel head gasket .016-.018 and check the math one more time Check out ebay #3216345883459. This maybe why I not selling parts out side my shop.
