Hey guys,

I did some searching and found a couple guys saying heads for 250 shot.

I have an HKE built 347, with rings gapped for 150 shot. I'm using AFR's again with a stock thickness Cometic gaskets.

From my last setup, I have ARP head bolts.

My question is, will the ARP head bolts be enough to hold down a 150 shot? The last thing I want to do is push water so if you think head studs are the way to go, let me know.

Thanks

Any other opinions?

No. I went with head studs on a stock engine. They are reusable and hold MUCH better.

I went with bolts just to keep things simple, I'd imagine the studs are better, but are they really necessary? I head of people spraying 200 shots on stock head bolts. So I'd think the arp's would hold on anything not much bigger. The bolts are reusable too, I think the studs would be needed for a much bigger horsepower car with forced induction. But bolts would be fine for a not so extreme build.

^ See this is what I was thinking.

I like studs because you don't run as much of a risk of pulling the treads out of the block.

Yes they are neccessary....why spend all that money on building an engine then cheap out at the end? Of course people have ran bolts and been okay..but is it really worth saving 100$ now and risking your engine down the road? I went with them now and I dont even need them..its just an extra piece of mind..and its worth the extra 100$

+1 to that. I am not even running a bottle yet and not considering blowing my new motor over the simple fact of a little extra money and reassurance. That's like putting a big cam in a car and leaving the stock lifters with 60-70k on them. Would they work yes, but how long will they last and what happens if you want to up the shot in the near future... Always plan long term and not what you just need now. That is more of a budget build instead of wasting money on something you may swap out to later on anyway. Makes sense you know.

Do I get it right, that I better leave ARP bolts and not switch to studs if I don't plan to re-hone the block?
I push some water now already but plan to up the boost more...

Get the Ebay ones, cheap as hell and work just as well. Everything is made there now anyways.

A 150 shot and I have ARP head bolts in my possession? That's what I would be using. A 250 shot on stock bolts is not going to be an issue.

IMO OP, I would just use the ARP head bolts since you have them. No need to spend more money.

^ for what your doing the bolt are more than enough.. yeah u can over build but in ur case its not necessary. Many people have had good luck with bolts spraying 200+ including myself, imo use what you have and spend the extra money elsewhere

Same here. Sprayed a 150 on a stock setup for years. Now I have have a stock bottom end with Arp rod bolts and Head bolts. I agree if you already have the bolts theres no need for studs with what you plan on doing.
