pre long tube install checklist Have my headers sitting in the kitchen now. Got new gaskets, O2 extensions, plugs n wires and true dual kit also. Those who have been through it before what am I missing? 01 firehawk btw. Thanks
Id absolutely, 100%, positively, do poly engine mounts while the headers are out!!! Its a no brainer from a maitenance stand point and also keeps the added power from damaging the stockers more than they probably already are. I have dd my last 3 fbodys over 100 miles a day with poly mounts and had absolutely no adverse effects on engine vibration or anything else so no worries there. Id reuse the stock header gaskets as they almost never go bad. I have reused stockers on 2 different 170k+ header swaps with no issues. Last ones had 234k on them still going strong with a Vortech supercharger for the last 50k or so. Get new header bolts and use a little silver antiseze on them and the plug threads for ease of removing in the future. You will probably want to ditch the o2 extensions as they tend to go bad at the worst possible times causing big time fueling issues and make the car barely driveable at best. If you dont wanna repin the rear o2 sensor wires inplace of the front ones in the computer harness then Id suggest getting o2's for a 2002 zo6 corvette. They have longer wires and better heater elements in them. That should get you giong in the right direction.

I ended up going with stock motor mounts and stock transmisson mount. I have no experience with poly engine mounts but I do with poly transmission mount and it vibrates and gets worse with age and mileage. Would only use the poly trans mount if my car was just a drag purpose car.

Big difference between the Prothane and the energy suspension poly trans mount... I ran Spohn solid motor mounts and Prothane trans mount and noticed no difference myself. The ES is known to cause unwanted vibrations.
My buddy has a prothane and its hardly noticeable. I ran an ES one for a bit and hated it very stiff and vibrated everything in the car. I run a stock rubber one in back now with poly MM's and it drives just like a stock car no added vibes, until the cam went in lol

Mounts aren't in the budget for now. I may get the header bolts though. And I'll have new O2 sensors by the time we install. Any part # on the vette ones? Will be getting tuned within a month or so.
