I understand turbo ..... and I do agree .... I beleive in the insurance policy .... do it so it dosent become an issue... and the its nearly a wide open fun time after studs ... up to I beleive most start doing firerings at the 500-525 line ... what I was told as a safe line to draw ....

 

ive never heard of having to get any machine work done when installing 4k gsk and what are pedistals

 

I think he was meaning for the head studs.

 

studs require machining .020 off the rocker pedestal so the washer and nut assembly clear the valve cover

 

huuhh ok I did not know that but thanks. So the next logical step after 4k gsk would be studs then what after that?

 

depends on what you want the truck to do

 

go fast haha reliably

 

my understanding from the guys at Dynamite Diesel products here in Washington and multiple other reputable shop's is that studs then 4k .... the pulsation and pressure caused by actually spinning 4K can overcome factory head bolts in some cases ...

I would save my self from having the possibility of the HG going south is my reasoning for the stud before 4K ... if he wants to do 4K then stud ... I would not recommend it .. especially if he has done timing mods and fuel .. has already has 1 of the 2 ingredients needed to pop a HG ...

I understand that like you turbo I too have much engine building ( 60 series,8v92,6v92,8v71,C15,3406,3126, ETC )...

Better safe than sorry is my Motto

Rocker pedestal's get milled .200"


SO from the end of the pedestal with the bolt in it .. 1.10" towards the rocker and .200" down ... torque in sequence ( 3 equal steps to 125lb/ft. ).

This will be my first HG in a 12V but I have rebuilt a few 8.3's in the past as well ... almost identical .. just a bit smaller is all ..

Got a cylinder head 6 injectors and a colander full of bolts ..... ( Boss asked me ) can u have this by tomorrow @5 ???? .. dang ... not asking for much are ya ???... oh and it was in a blue bird , front engine of course ... what a fun job that was

 

haha sounds like alot of fun my friend thanks for the infobtw any brand you preference for studs i dont know much about them and the different sizes and such. Ive heard that arp has good ****. I just dont want to spend a fortune on em.

links would be helpful too

 

I recently bought mine from E-bay ... 417.00 .... ARP 2000's ... will be installing in the spring ... just hope she stays togeather that long ... been stayin off the happy pedal , and i backed my fuel plate off a bit ... and the star wheel too ...
