427 head questions...

291 heads ARE square port. I need to proof read my posts closer. Thanks for catching the mistake.
We do not see either 840 or 291 heads at swap meets in this part of the country anymore. All the 840s I remember seeing were early 69 cast dates. I do have any extra set of good 291s.

I was just curious to see if the older 291 heads carried the same part # as the ones that are available in the GM Performance Parts catalog.

Does anyone have a set of the newer 291 heads? If so, are they the same as the old heads?

We currently have a 69 375 Chevelle that we are doing some minor touchup work on. It is a June car with F-23-9 840's on it...BKH

Thanks for the info guys. Just kind of wondering about something I read.

Our COPO Chevelle was shipped from Baltimore in late July. It has the 840 heads. However, the engine was built in early April. Obviously the heads were cast even earlier. Just because the car was built late in the year doesn't necessarily mean that you have a late year engine. It is my understanding the 291 heads were built with both large and small plugs. What heads did the late year L78 Camaros use? Were they large plug 291s? Correct me if I am wrong.

Hello everyone,
I have come across a set of 074 heads that look to have some cracks in the water jacket areas . Any idea what i should offer this guy for them? I will call my machine shop monday on what it will take to fix these, I just figured the castings were worth something. They are dated 10/69 .Thanx for any help with this question.

Over the past year most sets I have seen are ~$1,500-$1,800 for a fresh set and $1000 - $1200 for a set needing a valve job. I picked up a pair for $600 which were bare and needed new guides, but were not cracked or ported. Based on my experience, I'd say something less than $500.
