from another forum Wrote:what does "tumbling" the head consist of? Is it similar to tumbling bullet casings? Not sure (tumbling bullet casings...???) What "tumbling" means in this case is they have a large tool - it consists of a large cabinet, with a rotisserie that you strap the head too. The cabinet is closet, and it tumbles inside the cabinet.

OST-064: Breathing on a 3 rib
everything is back in my hands for final assembly....
head, with fresh valve job (machined .008")... ![[Image: AEU86 AE86 - OST-064: Breathing on a 3 rib]](http://ost.ebeans.ch/albums/userpics/10005/ready_for_re-assembly~2.jpg "AEU86 AE86 - OST-064: Breathing on a 3 rib") along with assembled short block - those are Molnar Tech 40/20 H- beam rods ![[Image: AEU86 AE86 - OST-064: Breathing on a 3 rib]](http://ost.ebeans.ch/albums/userpics/10005/block_top_and_bottom.jpg "AEU86 AE86 - OST-064: Breathing on a 3 rib") Does anyone see the remnants of a problem in the deck??? It took a great deal of decking to get the block suitable to accept a metal gasket.... so much so that our deck is now .018" (piston above the deck!) ![[Image: AEU86 AE86 - OST-064: Breathing on a 3 rib]](http://ost.ebeans.ch/albums/userpics/10005/deck_-_piston_above_deck.jpg "AEU86 AE86 - OST-064: Breathing on a 3 rib") The "fix", Cometic C4166-051, that should set the squish back to .033", or just a tick above .8mm....... More to come.....
