Will only 67 heads work on a 67 400 block and intake? I have always heard that you can go back in years but not up?o No: o No:
go to the wwwatlantaBUICK.COM AND YOU WILL FIND THE INFORMATIOM YOU NEED TO KNOW. vERY INFORMATIVE SITE. ed
Thanks, but when I go to that sight I get a screen that they are coming soon. I am unable to navigate the sight. Do they have a different address?
I have gone to the Atlanta Buick GS page and do not find information about heads other than numbers. I would still like to know if other year model heads will work with my '67 400 block and intake? Any advice is appreciated.
:Smarty: Lamar: If you don't get your answer here, I'd say to call TA Performance and talk to either Dave or Mike T. You won't get better info anywhere.(www.taperformance.com) Don't quote me on this but I think that the issue is one of proper oiling. The heads you have oil the valve train through a passage in the block that runs through the head gasket and into the head, then through the rocker shaft pedastels and through the shafts. The modern (more modern, not that yours are antiques:grin: ) heads oil in the conventional manner, through the lifters and pushrods and then onto the rockers, etc. I can tell you from personal experience that there is a potential failure issue with the early version. I also have a 67 GS 400. Mine sat for many years before I purchased it. The engine was already out and partially disassembled when I bought it. If the evidence is anything to go by, the oil passage through the head, or possibly the rocker shaft was leaking oil. The engine was obviously a high miler that had not had it's share of preventive maint. and had buit up a rather large deposit of oil/sludge/yucky stuff (the technical term:Smarty: ) and eventually the shaft failed in a rather spectacular manner with broken rockers, bent valves and other sundry bad things. Talk to Dave or Mike T. You know it isn't opinion but 100% fact coming from them.
Thanks, I will give them a call this morning. They have helped me out on a couple of other issues in the past.
For anyone that has been following this post, according to Mike @ TA Performance, heads can be used between the '67 and '69 model years for the 400 engine. The oiling system is the same to the rockers.
