Fel Pro Header Gaskets - 1406 or 1470

Which do you guys use? It looks like the 1406's have bigger holes, I'm wondering if they'll be more likely to leak. They're also a bit cheaper than the 1470's.

Felpro 1406's will not leak. I ran them on my 94 for 6 years with no problems. I recently matched them up to my ported heads and I'll actually be trimming them slightly. They are a perfect fit.

I have used the 1406 for over 10 years. Never have a problem with them.

Yep. I've used the 1406s for years with my MACs, Jet Hots, and now LPPs.
