here's the stainless exhaust flanges i had cut with a water jet.they will fit 2"od header tubes.the pypes headers i was using were puny and choking off the motor.see the difference in the pics.

here's the torque plate i had cut with the water jet.it's bolted on when honing the block to simulate the head being bolted on and the stresses and distortion it causes.

heads are 75% complete and looking great.also found head bolts that are almost as strong as the arp studs and 1/10th the price.the stock head bolts are torque to yield 12mm torx head junk that caused me a real pita to deal with and the arp studs i need won't be ready for some time from the manufacturer arp.so i have been looking for an alternative and i found 12mmx1.75x140mm grade 12.9(176,000psi) socket head cap screws at fastenal for the huge sum of $2.15 each.the arp are 200,000psi but are originally made for a 5.9 cummins diesel with 60PSI BOOST so i should be ok with the ones i bought and 18psi boost.

this is a mockup of my header collector and cat arraingment i am thinking of using.this will be for full length headers but i may still make them a shorter style.will wait and see what fits best in the car i guess.

got my custom made hardened 4140 head washers from the machinist,got my v band clamps home,ordered two more stainless cones from cone engineering for my headers.heads will be finished by sunday.gonna shim the springs a wee bit for some added insurance but honestly with the lightweight titanium valves i should be good to go.waiting for the block to be bored and the crank to be balanced.
