Default What headers will work with AFR heads?

I wanted to purchase Hooker 2149's, but found out from their web site that they will not work with AFR angled heads... Any suggestions?

:banghead:

Their bigger heads (220's and I think the 210's) come with what they call a bowtie spark plug angle. They angle the spark plugs down more, causing the spark plug to hit the header tube. You can get the L98 spark plug angle optional on the 210's and smaller heads, and they will work fine with any header.

One more question... What Y pipe will I need for my '85? I see that the one they reccomend the (16720) is slated for '86 and up...

The difference is in the flange on the converter, you must buy the 86+ Y-pipe but you will probably have to weld the flange from your stock converter to it.
