A couple of months ago, someone had posted some info about an aftermarket manifold that would work with the Z11 heads. A google search on that info yielded no good hits, does anybody have some specific info on these? Or better yet any user feedback?
Thanks
Hmmm...date codes...as I recall they are 61 or 62. The heads are in storage in Reno NV and I am working in Phoenix AZ right now...I beleive they do have cast dates and the snowflake foundry mark...any info on these head part numbers???
Thanks for all the info guys!
Thanks guys. My heads are hand stamped with part nubers in the center location. One head is stamped 0223806 and the other is stamped 223806. I was curious because I have an old Car Craft article referencing the Z11 1x4 NASCAR setup and there was no reference that I found on 348-409.com for that...
Hi all!
When I had first traded for these heads/parts about 20 years ago, I had to search long and hard for info about these parts back then. Glad to find this group! I had originally traded a '56 project car for these parts plus other 409 engines and Chevy goodies. What I have left are these...
