VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 Those Heads Again

All this is very interesting reading. To answer gmccorkelle's question about whether the real early heads are the same as 25-27 heads, they will fit but do look different with the back of the head being rounded from the top to the bottom, this head was fitted between 1915? and 1922. My 1915 Amesbury has a 407 head and the casting date is 1922 so it must have cracked and been replaced. I'm also fortunate enough to have 2 of the 3 port F series heads which I will use if the single port head becomes unservicable.
Just a short note for the Aussie's. When replacing the 28 two part exhaust manifold make sure you either check or preferably machine all the mounting surfaces as the twin port part will crack in the middle of the Y and the single bend section will break of one the mounting wings. Also it is recommended to use copper caskets if you can as the manifolds move a bit with heating and cooling and the after market gaskets can grab and cause the manifold to crack.
I've never seen a 28 cracked head in in 40 years of mucking around with 28 Chevs

I notice you say you have a couple 1928 RHD 2-piece exhaust manifolds. I am looking for the 'Y' section to buy so I can use it as the header piece for my speedster. I want to end up with a racer style outside exhaust system. Let me know if you will sell. Thanks.

I can help with one, it needs two broken studs removed otherwise ok. I'd have to get a shipping price to you. Reply by email if you want one

I have sent a couple of emails with no responce, have you received them? No longer interested?

I did get one email, which I replied to, but no more. I assume from your post that you don't need one now

Hi all you head hunters out there(LOL).I have had luck having heads welded at a local welding shop,but just heads with the small crack between the middle two cylinders on top.You have to V the crack out(eliminates extra carbon build up the exhaust gasses deposited),preheat the head,weld it with cast iron or nickel rod,and slow cool it.I am getting ready to prep a couple larger cracked heads( 1 all the way around the single exhaust port,and the other one crack around first head bolt hole, and see how successful they turn out.Will post results.Regards,tinsmith_ray
