Installed my Headers/Y Pipe/Etc..
buy legit o2 extensions. i've used them on probably 10 dif header installs and never had an issue; rain, snow, sleet, sun whatever.
replace the plugs and wires.
install the poly motor mounts. i just did this. there is hardly any extra vibration. so little, in fact, that after a month of driving the car you don't even notice it. very little additional vibration. i am using the factory trans mount, it has 110k miles on it at this point.
installing the poly motor mounts did wonders for my shifting. either the factory motor mounts were worn out, or i needed some help..either way, it made the wot shifts much easier. i'm assuming bc the engine is not moving around as much when getting on/off the throttle.
reuse your factory exhaust gaskets. they are multi-layer steel gaskets. basically they will be in excellent shape or they'll be totally fucked, there is very little middle ground for their condition. i've used and reused factory gaskets many times. imho there is no need to replace them unless they get crushed or something while off the car. new ones are shiny, that'll be the only dif between those and your factory ones.

Aside from Granatelli's, at twice the price mind you, they also ohm the lowest.
I believe it's Nasty Performance that has a good deal on plugs with wires.
Are these what you mentioned?
The Best V8 Stories One Small Block at Time
Thanks for all the help guys, hopefully I will chime in after a few weeks.
Should drop car off Tuesday. If my wires/plugs are not here by then, just going to buy them at Autozone and just return what I ordered that is pending-- no biggie.


Now to drop off to buddys shop, and get my PCM tuned.
Gotta clean some more windows to make this **** back lol.

Honestly one of the best mods iv'e installed I think, it makes a huge difference. Hope this helps!

Good to hear, colin. I went the same route you did, car should be done by the end of the week.
Sounds great, absolutely great. Power up top is definitely noticeable.
Poly mounts, absolutely no difference in vibrations. Zero.
Highly recommend TSP.
