My tuner said it was an old dsm trick. Since I have a d series i can get the the headbolts easy. Can I just install the arp each one at a time? I want to have them in before friday and dont really have time to take the whole head off.

 

try it and see...nothing to lose

 

Tried it, it worked! Thing is crazy now. I didnt know lifting the head would lose power but it did. Im getting 10lbs instead of the 9 I use to get. Spools faster also. Now I just need to change the timing and find out WHY it lifted.

Going to the local 1/8 mile Friday, wish me luck

Thanks Earl for the response.
