BHG number three...

[daoshao]

once a vehicle gets old...bhgs are common....i had a 1986 toyota 4runner and a 1993 acura legend that all had bhg's. Replaced headgaskets on both.

full three inch exhaust, lex/550s walbro fuelpump, aeromotive fpr, 10 pounds of boost, MHG, gasket matched exhaust ports.

had the mixtures checked on the dyno?

could water, like rain, crack our iron block or any part of the head?

nope but plugs all showed rich (before the BHG) and EGTs never went over 1400 degrees.

How much torque did you apply to the head bolts? Please let us know where it failed when you get it apart.

yeah but i noticed with mine at WOT it was rich as all fuck but under that there are BIG holes in the fuel and ignition maps because they are shifted 20% in the wrong direction
