Correct.? Just unbolt the 19 bolts that hold the girdle. Don’t touch the black main cap bolts on the vvel ladder

Yeah, that's all I was trying to say...the guy selling the heads looks like he has taken the ladder apart (as in removing the black bolts)

Yeah he is a idiot. Heads are good though

So humidity makes a bigger difference than heat? Good to know. That means mine should have some more in it too, then

Did anyone else come across this problem, I would like to know what year they apparently changed to the beehive style valve springs.

Is your car a 13+ if so you need to call up jim
Wolf and get the correct size retainers,13+ went to a beehive spring. Just got off the phone with them

Thanks Elmo, I was able to get Ray from RZG to send me the correct retainers. I'm waiting on them now

Well, as I'm going to install timing components, I have these extra 2 short bolts...turns out I needed to install them prior to installing the cams...now everything has to come back off. This just took the wind out of my sails

Was only able to make 2 passes and didn't launch very well on either but still captured some good exhaust notes. Car ran a DA adjusted 13.1 ET at 109.5 MPH. Beat the SRT8 Challenger by over a half second.

After finishing up the cam install, I drove to Houston from Louisiana (the first day off jack stands & 350 miles) without any hiccups. Last time I had Moncef (Admin Tuning) tune my car we made 316whp/262tq on pump gas with UpRev, dual exhaust, 4.08 gears, and stock crank pulley. Now the car has a single exit g Y pipe from ISR, 3.69 gears, & ATI crank pulley. We made a nice 329whp/269tq on pump gas & 336whp/273tq on e85 with Ecutek. If I didn't do the work myself I would have been really disappointed in the gains compared to the rest of you guys that are killing it. With that being said I'm ready to make some good 1/4 mile times.

Congrats on the install, it’s a tall task. Are you expecting better quarter mile times than you had with the 4.08 gears? Or I guess why did you decide to change?

I’m considering upgrading my diff and going to 4.08s this winter so I’m curious.

Thanks and congrats again!

I've got 3 different diffs, 4.08, 3.91, and 3.69 & was trying to test all 3 last year at the strip. So it just happens that I finished on the 3.69, not necessarily meaning I'm going to stay with them...I'm gonna try all 3 again this year and make a final decision on them. I honestly think that the 3.91 are best for the 7at and the 4.08 for the manual 6 speed in the 1/4 mile. I can't confirm this yet because I didnt have everything dialed in like I'd like for consistency.
