Replacement V6 head bolts

The flange alone on the new bolts it larger than the head on the original bolts giving them an even larger bearing surface. I really don't see the point of the washers, unless its an ARP thing....

 

Reduces friction during torqueing the bolt allowing more accurate stretch of the bolt. Check the length of the new bolts. Sometimes they are manufactured slightly longer to compensate for the thickness of the washer.

Length of bolts without the washer is the same

 

Bolted the heads up with the washers, I figured they came with the bolts for a reason. Only time will tell now...

 

So can I re-use the bolts cause headbolts.com doesn't work anymore and arp doesn't seem to make them unless i missed it. Sooooooooo is there any replacement ones i dont know about?

 

TA Performance likely has a source for new ones, if you want new. TA Performance Products Inc. - Your Leader in Buick Automotive Parts and Accessories

Doh. They were mentioned at least twice in the previous posts.

I would reuse the old ones unless there were something obviously wrong with them. Pretty sure the TSM says nothing about replacement.

 

Buick V6 198 and 225 fireball cylinder head bolts

I used these as well. ARP says the washers are The Most Important Thing In The World and have Specific Recommendations of where to apply their Magical Grease. I went ahead and did what they say because I'm a rule follower.

EDIT P.S. I didn't replace mine, I just didn't have any!

 

I have an ARP head stud kit for a Buick 215 V8. They're the same lengths used on the 225, only you get a few extra pieces. The ARP number is 124-4003.

I have used ARP products on several different applications.If you go to there web site they list all the open stock sizes and then you can make up what you need.Main reason for washers is on aluminum heads to not crush the softer aluminum around the bolt hole. I did use ARP head bolts on my 427 FE FORD after I snapped a old stock bolt and could feel others turning and not tightening.New bolts torqued down like a dream.Fun to see all the fasteners they have on there site. mike

 

Yes, like a kid in a candy store, then reality sets in when you see the price list!

YEP!

 

Does this work: - cylinder head bolts 198/ 225 cubic inch v6 chbs-1216 #chbs-1216

 

Lol I am

 

The 198 V-6 used 11 head bolts vs 8 for the dauntless engine so maybe they just give you extra bolts to cover the difference. Not sure about length difference either. mike
