351w stroked 408 HELP!

Hey guys I have a 351w I built to a 408. Now I was having high compression issues so I added cosmic .92 think head gasket to solve my problem. Well now the intake does not line up with the heads. Is there a spacer to add there !? Or what have you guys done ? Thanks !!

Hope it's 0.092" instead of .92"!!

If it's 0.092" you should be able to have the intake machined to fit!!

BTW....Welcome Aboard!!

You can buy thicker intake gaskets.
These are available in the following thicknesses... .031" - 125" - .200" They are a large port gasket. You can go to his site, and possibly call him for specifics. They are on the expensive side, and are sold as singles.
Custom Intake Gaskets - SB Ford XL - FlowTech Induction

Street port. 0.125" thick

Here is some of the rest of his gaskets.

Ed is VERY knowledgeable about what parts work, and do NOT work well on the SBF. He is also well versed in the 'gotchas' that tend to pop up when build various combos.

Good Luck!
