I installed a Vortech earlier this year. The first time out, I stepped into it a bit and it knocked like crazy so I got back out quickly. Brought it home and it was dropping a cylinder on the driver's side. I backed it back out the next day it here came the white smoke out that side. I took the heads off and it looked like #7 was the problem. While I had the top off I decided to install some Twisted Wedge heads, then put the Performer intake back on. I followed the directions and torqued everything back down, fired it up and the white smoke still started rolling. My question is, Is it possible there is a problem in the lower end, or did I just not getting everything back correctly. Thanks for your help!
