Some help you are!! - I'm already *very* confused!!
Dear Steve (Dr. Frankenbuick,)
Don't do this to me!! For 2 hours I thought I understood what was going on :hurray:. . . then I made the mistake of looking a little more carefully!! :eek:

Well, I can't understand what happened, but I *thought* I posted the conclusion that was going to stick with the existing exhaust manifolds on this forum topic. So I'm committed to the TA performance stage-1 heads. Aren't I? :confused:

*Gulp!* Hang on a second. Which TA Performance heads will not work well on the Buick 430. I realized this afternoon that I need the stage-1 heads in order to work with the car's existing exhaust manifolds. Will that work or not?

Is that something I should think about? I was planning to simply used the stock exhaust manifolds "as is" beyond some simple cleaning and machining to assure flat contact with the heads.

Well, you see it is *very simple*. At 2:45pm . . . I thought I knew what I was going to have done . . . . Now one key piece of this scheme has been thrown out the water!! *So* . . . This late in the day I'd better punt before I get myself into more trouble!! :clonk:
However, tomorrow morning . . . . the questions will start coming out!! :bgrin:
So stay tuned for the latest saga in this soap opera!
Thanks again to everyone who has tried to help me on this great Buick engine caper!! it ain't over until its over!!
Cheers, Edouard :alc:
Thanks - needed to check TA Performance footnotes!

Yes indeed you are right. Actually I had partially stumbled on the right answer yesterday afternoon. However, to get the right TA Performance "Stage-1 street eliminator" cylinder heads, you need to read all the footnotes on page 8 of the TA Performance catalog. Paul Muller recommends going with the 2" Intake and 1.650" Exhaust valve openings for this 430 engine. Also, the head requires the 455 lifters and pushrods (per another footnote.) So this is definitely not a case of ordering a part number and getting something that will fit!

Okay I need to check with Gessler and see what's involved with that. Ted Nagel went that route and was very happy with the results. Given all the compromises I have make to get this engine to fit, this may be the best way to balance all the priorities!
Thanks again and yes, there are more questions . . . but I have to write up all the specs first!
