I know about the thin metal plate to block it between the intake and head. This is going to be a performance type street engine.
And I am all about fixing any weak areas and doing no/low cost mods.

I'm talking about filling the passage in the head. Has anyone done it and what did you use.

I just got to thinking about one of the weak areas that are prone to cracking and my mind kinda went in this direction..
I'm thinking I need to spend more time block sanding instead of thinking..lol

Thanks
Dave
