See my post above (#4) for pricing.

The standard ones that I posted the pic of run about $50 and the ones that have both the 525 and standard BB pattern run around $80 per set

Remflex Gaskets !!!!!!!! THE BEST
They have double the compression than any other gasket NEVER NEVER leak , they make up for uneven surfaces corroded heads or Ex manifolds, reusable, never burn

Scott, I'm still trying to wrap my mind around how a leaking header gasket can contribute to reversion. When the piston is on the up stroke, the gasses take the path of least resistance, with part of the charge exiting through the leak. On the down stroke, if the exhaust valve is off its seat, it is a similar situation - it will try to pull the air in from either the leak or the exhaust primary. If it pulls it in through the leak, it's not going to pull any water in with it, unless the boat is under water.

Is it more a matter of less positive impulse through the primary tube into the collector? It just doesn't make sense to me.

If that was for me, then yes you certainly can get them through me.

Here's another one to fry the brain.

Why would a header with too large of a primary ID cause more reversion ?

Thanks. I read too fast and didn't read the last paragraph I guess. Mercury ones are indeed over $31 each through Bam. I found a trusted source for $9 each.

Not really. Best way to understand something is to think it out, even with help, vs just being told.

So, my question goes into the same sort of reason.
