Plug choice for Vortech with lower compression pistons?

[hus]

Just checking to see if I should be running something different. I have the NGK tr6 plugs with .030 gap currently. But now my internals are forged and I went with a 9:1 compression piston and I have a Vortech V-2. Should I be running a different plug or a different gap with that compression?

TR-6s, no need to change plugs

Thanks. But what about the gap? Is there a need to adjust the gap given the compression? Or does that not really matter?

how much boost?

.030-.035 will work fine.

How can you give gap advice when we don't know how much boost. If he's only running 8lbs, he could run up to a .040 gap. If he's running 17-18psi, he might need to drop down to .028.

More info is needed for a precise answer.

I haven't had a new tune since I forged the internals but prior to the build it was tuned at a conservative 6psi because I'm still waiting on installing an intercooler. My intake temps are what fried my stock pistons to begin with. As soon as my intercooler goes on I plan on a tune at 10psi.
