I have a chance to buy a set of heads for my '58 vette with cast of #37488770 which the NCRS book says are correct for all '58 283ci vettes, period. It is the only # listed for '58 and not any other year. I have another guy who has a set of heads with cast of #3731539 which he claims were used on '58 vettes. The NCRS book says they were used on '57 283HP FI vettes ONLY. It is not listed for any other year. He claims he knows better than the book (I used NCRS Pocket Spec Guide) and that the NCRS book is all wet and has been since he's done this stuff for 30+ years. Both head sets have X58 on the side. The 770 heads are twice the price but I'm going to make at least the motor in my car correct since I'm going to get it redone anyway. I highly doubt he's right but it's worth asking the question. I know, # again!

don't know the numbers, nor do have books that tell me what there are. but the NCRS manual has yet to let me down on what is the correct numbers for parts

Forget it. Do your own research.

I'm not looking for anyone's opinion for we all have them. I'm looking for someone to verify the fact that what some consider the "bible" is correct for I'm sure there are other sources. There are members here such as JohnZ who is a class act and freely shares his vast knowledge with all and one of the few that I would consider a disagreeing opinion as relevant. I'm sorry if I haven't grown up to be a mistrusting cynical person but it's not my style and never will be. Just because you get screwed a few times in life doesn't mean everyone is out to get you. I actually used real time communication skills with this person and I couldn't conclude that he didn't believe what he was saying wasn't fact. Thanks for your reply.

Another source book (Corvette by the Numbers, pgs 128, 132) agrees with the NCRS book. The 770 head was used in 58, and the 539 head was used in 57. Not an expert, just using a reference that I've found to be good in the past.

The NCRS.Org site would be the best place if you want NCRS advice or confirmation, IMHO.

Psst... Terry. I love JohnZ as much as anybody else on the board but there are quite a few others around who are pretty dang good too. Jerry B is one such person. He provided you the answer you needed and you dissed him because he asked you a logical question. The fact that he laced some sarcasism into the responce shouldn't bother you.

Think about it dude. You have the book with the correct number in your hand. You gonna trust an "unknown" party if they say otherwise? If JohnZ is the only person you want to answer your question, just email him directly.

The nice thing about this forum (or others) is that if somebody is dishing out bad information.. somebody will jump in to debate the issue.

I found that out the hard way I posted some info I thought I knew, but it truns out I was wrong and a couple of other memebrs were quick to point out my mistake. I leaned something new that day.

trw58c1,

Jerrybramlett knows his stuff. He as asset to this board like the rest of the Crew. He just does not candy coat the answers.

Joel 67

I agree.

TRW, I think you are the one who needs the chill pill.

trw58c1

Sorry to all for the offensive remark which must have hit a nerve. It's what I don't like about emails. I felt whipped for asking a simple question and will defer in the future. I have communicated with JohnZ and some others with private emails in the past. I didn't mean to slight any other members intellect in this area so I apologize. There are many who post here who have valuable information and are willingly share it with all. I do not have a book but seen it at a dealer I stopped at but will make sure I get one. In the future I will do more reading and less typing.

trw58c1

Please accept my apology. It is all I have to offer.

trw58c1

Comment accepted.

Thanks -

trw58c1

Constructive? I apologized. Just feel gang raped but it's OK, I must have deserved it.

project63

Appreciate the humility Terry. I don't think this was intended to be a dogpile, but Jerry has help many us out in the past.

The words we write can sometimes be interpreted differently than we meant. It's much easier to capture a persons intended message when we can hear the voice and read the body lanquage but hey, enough on the semantic sermon... lets talk about Corvettes..

p.s. Project63 - I live about 20 miles from Towanda (Valley Center). I assume you have a 63? Coupe for Vert?

Your apology is certainly accepted, but I also realize my response was not as polite as it should have been. Here's what I should have said.

The NCRS spec guide was first distributed to members in 1989. A whole lot of work went into it. Since then, many smart people have questioned, re-investigated, and debated the information it contains. However, I can't give you a single example of a glaring error that has been found. The corrections over the years have been more like clarifications of documented assembly line abnormalities. A mistake on the order of a completely incorrect cylinder head casting number... well, I just haven't heard of anything like that.

A 539 cylinder head is not rare in my opinion. Finding any 770 casting is pretty unusual. A matched pair of 770 castings that haven't been ported, decked excessively, had larger valves installed, or had the mounting holes chipped from over-use, is extremely rare.

I really do appreciate the kind words posted by you others. Most days I'm not sure if my own family is listening to me at the dinner table. It's very good to know some of you read and appreciate my posts on the internet.

I always enjoy reading your posts, Jerry. More importantly, I LEARN a lot from reading them.

You've forgotten more about Corvettes than I ever knew.

Didn't see you in Orlando/Kissimmee. Did you go? Chuck

Well Said Jerry!
