What Carb for Poly Stroker

Yes it will bolt up but I bought this Edelbrock spacer after watching a video on Youtube of some guy reviewing the AVS2 who reckons it's a must to avoid heat related issues (vapor lock etc) due the aluminum construction. The spacer is due to arrive Monday.
I thought about putting the carb on this weekend onto my existing aluminum spacer/adapter (or straight on the manifold) and then swapping it next week but I'm older and a bit more patient now, so I'll probably do the job just once after work on Monday or Tuesday.

Those wooden spacers are supposed to be da shizzle for keeping the carburetor cool.


I've always run this 5/16" thick gasket with no fuel boiling problems...
