I'll be sending out my front carb to get rebuilt/re-plated at the same time as the other two I'm purchasing to complete the set.

I'm just having fun learning everything I can about this early all-iron Pontiac 389.

Cool!
I have a 455 I recently purchased, doing similar work to. FWIW, auto trans fluid completely loosened all carbon deposits in the chambers. Previous owner poured some in each cyl., at my request.
I removed both heads a couple weeks later, found 2 cyl's rusted up, but will clean up @ .030 . I filled up each cyl. up w/ ATF and reinstalled both heads, lightly tightening them with 1/2" impact (put old head gaskets back on).
Cyl's should be a little better, when I get back at it again. On the good cyl's the ATF got past the rings and into the pan. The old head gaskets are holding the trams fluid in the cyl's, not leaking externally...

Was hoping for a runner that I could put some rings in and experiment, but engine is the best 455 I've found, will eventually serve a purpose...
I had a hydro magic in a 64 Bonneville, was cool, first gear was like 4:1. Wish I still had that car...
