And tried to Drill it out , Tap and Helicoil it, but the Helicoil wont hold.

And i dont trust it running High RPM's anyway, so i need a new head.

I currently have stock 5.3 862's.

I have my cam , and am going to do a front mount Turbo down the road.

Should i just buy a used stock head?

Or should i upgrade to a better set of heads now?

What if any do you guys suggest?

I cant afford to break the bank, but am just looking for a nice upgrade since i need to change a head anyway?

Thanks!!!!!!!!!

 

How did you break a rocker arm bolt off?

I would say look into patriot heads, for the money they are a good choice.

 

If you have the time and extra money you should just do the new heads now. That sucks that happened to you.

 

I over tightened the bolt, i think it also had a "bad spot" or imperfection in it.

And yes it sucks


If i can afford it i love to upgrade, even to a better factory head if Possible, just need advice thanks!

 

imo buy a stock head for 50 bucks and run. What the point of expensive heads when your gonna blow air through it. Just my 2 cents

 

If you had the budget I'd do the patriots, but that's a tough call. TJ probably has a set of 862's sitting around.

 

I have a set of 317s that just had a valve job done with less than 50 miles on them I'll sell you cheap.

 

I agree, its not gonna be as important seeing your gonna be going FI and shoving air down its throat.

 

Hard to beat 317s

 

If he does 317 heads he will drop about a full point of compression. which wouldn't be good for staying N/A.
