headgasket problem????????

[scotty]

Blew another fel pro 9333 pt1 out today. I blew another one about 6 weeks ago. I have a dss 306 with trickflow heads arp studs S-trim 16-18 psi I have a pretty safe tune just went to the dyno 3 weeks ago 510 rwhp. Both head gaskets blew out in the exact same place number three cylinder. If you look right under the spark plug you could see the chunk of gasket sticking out. It blew about a 1 inch piece out. That was the first gasket. This one looks the exact same way. I happend in third gear under full boost both times

What could be the problem. Do need a better gasket. There must be something wrong for it to do it twice the same way.

Any ideas?


Thanks
Guys
