- Rebuilding a Chevy 6 head. Head already has new guides installed and hardened exhaust seats installed. We are cutting the valve bowls and performing valve enlargement from 1.72/1.5 to 1.84/1.6. This is one step in rebuilding a head. We sell complete heads with all performance modifications done. contact Tom@12bolt.com or go to www.12bolt.com Sound was wacked by CZcams 12:00-16:00 because of a radio playing in background

Looks like you are in full production! Love the Serdi!
Trying to be productive.
Nice Machineing!
Thanks!
**#*I have crazy ideas*#** sometimes, well most of the time, I was thinking about how the flat head guys would use the exhaust for the intake, so what if the Chevy i6 was done like this??? Basically bolt tiny turbos to the intake ports, ( previously the intake) then pit the largest exhaust valve possible, ( now the intake) keeping the new exhaust valve the same size, I never saw Webber carbs used with blow through?? But build a intake that is bc basically a short length of 3/8" wall aluminum tubing, joined by 1" tubing to distribute the vacuum, to the carbs, then build a plenum to put the carbs in! Some what like a sheet metal efi intake only with a large plenum, with 3carbs inside, and no throttle body on the plenum, just going to the turbo, it could have 3 inlets , if no intercooler, the turbos mounted to an extension, close to the head as possible, 1/8" steel, with about 3/8" steel flange, to the head, dropping the turbos lower than the intakes, then possibly my ake a 16 ga aluminum sheet heat shield to keep the turbos from cooking the intake charge, the 1" aluminum tube connecting the intakes, could be notched and welded to the intakes , so about 3/4 of the tubing looks like it goes through the intake, then mount H2O/methanol injection nozzles in the ports in that tubing like the injector in new manifolds, to keep the nozzle out of the airflow, preventing restrictions... Just guessing, but I figure the valves will be about the same size, maybe a 5angle valve job,. And maybe longer valves, to run larger springs, and get a bit crazy with the cam, it's probably not going to be a street engine, daily anyway, maybe even weld up the chamber with nickel rods, if you gonna be crazy, mays well get really crazy!! The new intake ports me at need a bit of reshaping, and the new exhaust ports may need some help to prevent reversion, but before getting too crazy, it would probably be easier and cheaper to cast a new head! Either from aluminum or steel so it can be welded easier!! Heck I'd like to maybe do try putting Subaru heads on one, H6 heads welded together, Rin the timing chain off the cam gear, just make a new timing cover from aluminum, similar to a diesel, so the timing gear and cam can run the overhead cam, if the bore spacing is off, just cut it and weld the head back together!, Then weld the block, the deck, with nickel, and re-drill passages and bolt holes. Deck flat, it could be interesting, a dohc, and 4valves / cylinder, it would basically be a vortec 4200! And ya can put a 2.8L V6 distributor in the 4200, then build a intake for a carb, Soo much easier, and buy one running for about $250-$400 +/-, Soo much cheaper, and makes more power, about 270hp stock, with boost about 600hp stock, I told you my ideas are crazy!
Show, parabéns pelo seu trabalho Tom.
Thank You. We enjoy improving these engines.

Crazy ideas back, maybe do the swap with the integral intake heads, cut the intake off, weld on a t3 flange, converting the intake port to exhaust, make an extension, that drops the port about 2" then bolt a small turbo on the extension, make an aluminum spacer for the intake (the old exhaust port, that does the opposite, raising the port, and up to about 6" long, raising the ports to about 3-4" then mount the large plenum, to fit side draft carbs inside, then a bolt on cover with inlets that allow the turbos to directly connect, maybe connect to the bottom of the plenum, allowing the cover to bolt on, and be removable without removing the turbo plumbing, about like a 2 piece timing cover! Crazy idea!! Any opinions, other than 'you Krazy!'
Sent an email your way to hopefully get my chevy 250 head your way. Hope to hear back from you!
I have seen no email mine tom@12bolt.com
@@telowe2000 hopefully this one goes through to you
Is this one of your new toys(machines) tom?? Looks fun!.
Serdi 4.5 Had it for 1 year. Great tool for doing head work. Possibly the best out there.
Do you do any 300 Ford stuff ??
Sorry, No
