First, gaskets, did you use the OEM ones, the ones that came with the headers or some aftermarket ones like Fel-Pros?

Secondly, would you recommend a FPR? I've heard some people and saw a dyno sheet that leaned the car out after the install? What PSI should be run after the install?

I have yet to notice my car running leaner after the LT install. I now have a puff of blue smoke at very low rpm's/low engine load coming out of the left tail pipe, but my oil has not budged since the install.

I went with new Ford OEM gaskets for about $9 each.

HTH.
