AFR lists the 215cc RR (my heads), 210cc, and 220cc LT1/LT4 heads as using Fel Pro #1406, but the 180, 190, and 195cc heads are listed as using Fel Pro #1404.

But on the SBC install page, it says...

4) EXHAUST GASKETS:
Fel Pro #1404 exhaust gaskets should be used on all street heads. (190 & 195). With minor trimming Fel Pro #1406 may be used on the 210, 220, & 227 standard exhaust heads. For spread ports #1409 should be used. Do not under any circumstances port match exhaust ports to match gaskets. Reverse cool applications use GM gaskets only.

I don't think very many people have 215cc RR heads like mine, but some of you have to have 210cc and 220cc AFR "LT4" heads, so which exhaust gaskets are you using? GM or Fel Pro?

Second question... where can I get a set delivered to me by Wednesday evening?

I doubt anyone is going to have them locally, although I know one shop that might surprise me. I figured I'd just order online and pay for next day or 2-day shipping. Any suggestions? DON'T say Internet Racer's Supply.

 

JEGS has pn#375-1406 D-shaped, Brodix Track 1, port size 1.55" x 1.63" gaskets and pn#375-1470 Chevy LT-1 and LT-4, port size 1.39" x 1.41".

I sent an e-mail to Mark, but if anyone knows, don't be afraid to speak up.

Thanks!
