Ok you guys see my sig, I'm a 13 degrees timing. I can fuel my 64/14/71 to 45 lbs running through the gears and hit 50 very quickly if I mash it at 85-90 MPH ( waste gated at 50 ). My egts get hot in a hurry with my setup, Im guessing due to the timing. On the interstate at 110 MPH and around 3200-3300 rpms shes still fueling hard and smokin. But the EGTS skyrocket. I have all 12 valves with only 20,000 miles on them ( not reground, bought brand new when installed ) silicone seats and retainers. 60 lb springs head gasket I put in with the new valves, used head bolts ( spent all my money on new head and valves ), this was all 20,000 ago. I know my EGTS will lower, top end power increase and most the ins and outs. But will I see a noticable gain in HP, fuel economy and egt decrease. enough to justify the head pressure gain? let me know yall, tryin to learn the best I can and thats from the experience you guys have

 

anyone out there

 

I would say yes set it at 19* and retorque the head
