Gasket blew at track

[PWR_RYD93]

The last time on the dyno was a long time ago with the stock 3.5" Novi pulley and my old school ported Edelbrock heads... so only 15 psi boost. HP was just over 560 HP, torque numbers were real high but goofy because of the high stall 9" converter. Best time to date with the new 205's and smaller pulley is 9.913 at 139.xx spinning my 12.5 x 28 ET Streets. My cam is an old AFM B-4 (same grind as TFS stage 2). More specs are in the user rides section.

AFR told me the 75cc exhaust ports work great with custom 1-7/8" or 2" primary Kooks headers, but are a waste with regular bolt pattern flanges (like my MAC 1-3/4's). I figure I will hand port my exhaust ports when I step up to some real race headers with the wide bolt pattern
