What won’t work!

[El Rat]

Hi gents
I know that there is at least a zillion things that won’t work but a few additions.

1. There is probably 6 different intake gaskets...only one will work on an 817 head
2. Inch and a quarter ARP bolts need to be 1.125 long
3. ARP intake bolts need to have the threads chased
4. The small metal exhaust block plates won’t work on the head side or the manifold side with standard thickness gaskets.
5. After you screw around with all the various “won’t work” iderations you need to chase the threads in the heads.
6. I’m sure there are more.
7. As a side note the local NAPA got me a Z intake gasket, by mistake, damn is that thing HUGE maybe 300 cc’s or more!
8. See attached.
