I've seen many posts regarding the Wayne Chevy 12 Port and am happy to have joined the Wayne fraternity. Contrary to some rumors the Wayne Molds have survived and new production parts will be available in the near future. The molds were acquired by Lynn Helm (Inliner #87) some time ago. The first run of downturn exhausts are done and in the machine shop. Please PM me for further information.
I've always been curious, are these heads for a 216 or 235. I always figured the former because of the era they were designed in, but were they ever updated?
The twelve ports were started by Wayne, bought by Warner and fianlly by a group. There were GMC and Someheads to fit either a 216 dry sump Miget engine of a ruch oval racing performance history and also more fr frag racing. now the heads and the support products for the heads are hard to find. But with the correct head work by Sissells it becomes a monster. Normbc9
Wow I was wondering if the equipment would end up with someone that could start producing them again. Pleas keep us posted on developments. this is great news for Chevy inline guys.
Seems much like the other Wayne pattern guy. Made some demo stuff, took deposits and then did not deliver. I made a mistake allowing the use of the Wayne logo. DW
Harry Warner and Wayne Horning (went to school with his and Barney Navarrs's sons) had a biz in Glendale Ca then split up. Wayne went up to La Cresenta faded away. Horning I heard waent to work on a 301 GMC 12 port pretty good success at the drags and Bonneville. Nice to hear the Wayne is back in production. Funny How Glendale had Navarro, Kong ignitions, Wayne, Kurtis Kraft midgets and big cars, the Godfather of them all Ed Winfield who taught Isky how to grind cams....all in Glendale way back when. I remember my Dad taking me over to Kurtis Kraft watching as they built Indy and midgets. The guy who did a lot of their uphostery lived across the street, went with him to snap in the seats a couple of times, too bad everyone didn't have a phone/camera 24/7 back then.
It's out of my range money wise right now, but I do hope this is something that become a reality. As long as it's usable on a pressure oiled 235 six.
This is not and will not be a repeat of the previous program. Heads will not be available until thoroughly tested and all parts are available. There is currently no target for completion and no deposits are being solicited or accepted. My original post was solely to dispel the rumors that the molds had been destroyed and/or lost.
I really can't wait. I'm going to start saving my money now. Im sure it will be a very limited run. Is there anyway to get on a list of serious buyers so not to miss out on buying one? Posted from the TJJ App for iPhone & iPad
The original Wayne Chevrolet head fit only 216/235 15 bolt blocks. The patterns were modified for later model 18 bolt (1953 ? or later 235 and 261 blocks) by Bob Toros in 1957 per the article in the link listed below. (http://www.inliners.org/12_Port_Story/pt_nine.html).
Now, lets get this clear. The article stated that the patterns were modified for the 261 block, but it differed from the 235 block. And, this was much later than the "changeover" from the early 235 era. I'll ask again because I have never owned a 261, will your head fit my '56 235 block? As I said, I jhave no experiance with a 261 block, and the article makes it ound as though a 261 head won't fit a 235 block.
NL...I believe, to run a 235 head on a 261 block, you just need to drill steam holes and use the 261 gasket. Similar to the 400 Chevy V8. And vicy vercy, I think you can run a 261 head on a 235 block...since the steam holes will simply be rendered inopperable 'cause they'll be blocked by using the 235 gasket...or they might actually need to be plugged. Lots of good info here. V V V http://www.jimcartertruckparts.com/Articles/261-Engine.php
The OEM 18 bolt 235 and 261 heads will interchange with the addition of steam holes to a non-261 style head bolted to a 261 block. One row of steam holes is actually drilled at an angle to penetrate the water jacket of the cylinder head, so don't know how the water jacket core is designed for these heads or not, but the steam holes would still need to be present for use on a 261 block.
A 261 type block will fit a post 1953 235. The major difference between early 216/235 and later 235 and 261 is head bolts. 15 for early 18 for late.
I'd like to get on this list as well if something ever did get setup. Would be Very interested in purchasing one for my 261.
