Which model gaskets? I've been running 1011-2's for about a year and a half, but I haven't put boost into them yet. That should be within the next month, or so.

I like their stock replacements the best. 8548-pt2 or 9333-pt1. Never had one go.

My guys swear by these.

Most times a blown HG isn't because of the gasket itself.
Alot of times it is an installation problem or a mechanical issue with the car that causes a blown gasket.

I fixed today a blown 9333-pt1. The owner of the car installed the heads without the dowels.

On my high compression 331 i use the 1011-2. No problems last 2 years

I agree, I did my research for my H/C/I and most recommend 9333-pt1. I've had them on mine for two years running nitrous and no problems.

i blew a set of felpro replacement gaskets (came with re-ring kit, not sure if they aare 8548s?) with my old untuned combo (thumpers, b-cam) and 9 psi

ran great but i didnt have any BTM or anything and was getting too much spark and ended up blowing a HG, took a few months but it did go.

currently i am running the 9333s and they seem to holding fine, got a little hotter combo now, TW heads and f-cam with 10-11 psi and this time i have control of fuel and spark so i am in the safe zone. no problems yet.

i would think 99% on blowing HG issues are more tune related or installation error than the actual gasket itself.

only 500rwhp huh, lol. The term "only" is really not fitting for that statement.

Detonation kills head gaskets, even a tank of bad gas and you could be in trouble.
Bascially if the engine ever goes lean, regardless of why, you could be in major trouble.
Torqued poorly is another reason.
Poor deck or head surface, anytime you pop a HG you should have the heads checked, even brand new heads sometimes aren't flat.

The only HG's i hear about failing because of the gasket itself are cometics.
