Blown head gasket

My 367 has run at up to; 11.3Scr/9.2Dcr/190psi with alloy heads, @.032Quench. I run a 2-stage timing curve; 12>14@ Idle, going to 28*@2800, then 32/34 by about 3400. This allows me to run 87E10 full-time. I run the 039 FelPros, with ARP bolts torqued to 105 in stages, on the ARP grease, with no retorque. In ~2005, I replaced the cam, redecked the block, and subsequently the Scr changed to 10.95, the Dcr to 8.9, and the pressure to ~185.
Your results may vary.

BTW
This change was deliberate. I gave up top-end power to gain bottom-end torque for my 4-speed/3.55s combo..
I got those gaskets. I will increase torque to 105. I am at 95 now. Hand tight then 50,70,95. I have same arp studs.
