So if I understand you have changed your mind to doing the 3k and going ahead and installing the full 4k. That is great you have finally made a decision on what you are going to do. Now you are in controll of the throttle.

 

Just dont be dumb. know its limits and stick with it and you should be fine.

Now I would never let Roger put 4Ks in that guys crazy................. JK Roger

 

Pdr sells a 4k kit with all 12 60 pound valve springs for 250 bucks that's hella cheap the kit comes with excelent instructions and if you have any questions mark has all the answers imo those guys got they're **** together

 

i got the gov kit for 80 shipped from tony and a good set of 12 60lb springs for like 120 shipped. thats a good 50 cheaper

 

I'm sorry it was 225 for pdrs set I just dug out my reciept I'm not saying to buy from them I'm just sayin if your gonna run 4ks get the kit with 60 puonders included it will save you money in the long run. Make sure you got the right valve spring tool tho 5 and six and the exhaust side of 4 are impossible without it I think its a kd 2048 or something like that. Oh and make sure you get all the washers out my buddy trashed a built. 913 because he didn't get em all out. Yes he built it himself

 

Have you installed the gov springs? Did I see an add that you are selling your springs or another set of gov springs.

 

no im tryin to sell them to get a air intake
