12 POINTCOMPETITION STYLE 34pc.HEAD BOLT SET WITH SPECIAL STYLE WASHERSFITSSBC CHEVY
12 pointhead bolt set with washers.The washers are a special type washer. Remember to install the washers with the flat side down against thecylinder head.The head bolts have an extended reach to compensate for the washer thickness. Beware of others offering a similar kit with standard reach bolts. When using the special washers the bolts must have an extended reach, as oe length bolts do not have sufficient reach to accommodate the thick washers. This is what we use on many of our engine builds. Zero problems to date. The 12 point head also allows for a tighter fit of the socket and less variance in the torque readings. Standard style 6 point head bolts allow the socket to round the corners slightly on the bolt and this will affect torque accuracy.
One of the most important benefits of the special style head bolt washers are that they distribute the pressure on the cylinder head, and provide a glide surface for the built in washer on the head bolt. This allows for much greater accuracy when torquing the head bolts. Those with aluminum heads must use the special style head bolt washers for two very important reasons. The aluminum surface tends to drag and gauldagainst the head bolt, causing inaccurate torque readings. The other well established benefit for the use of these washers is the fact that aluminum heads are known to crack in the center area of the head directly under the head bolt. This area has been compromised due to the port location. When the aluminum heads are cast it is difficult for manufactures to keep the integrity of these areas consistent. The washers positively reduce cracking the cylinder head in this area.
Those wanting to run just the special washers with conventional length head bolts will not be able to do this due to the thickness of the washers, as the standard head bolt length have a very limited reach. You may think that GM stocklength bolts have enough thread on there bolts to add washers, but this is not the case.
We strive to keep our prices low, and due to the high volume that we purchase, this allows us to have the best price in the country. Many garages will buy several sets at a time just to have them if the need arises.Our shipping prices are usuallythe lowest you will find.

Very Important Note From Our Company President, Skip White.
It is my strong opinion that if you are building an engine in the 375 hp or greater range that you should use the ARP brand head bolts. They are far superior in every way compared to the head bolts listed in this ad. The cost to move up to the ARP head bolts is only around $24.00 additional cost. The washers are included in the ARP head bolts and they actually have a chamfered area that mates up with the radius in the head bolt very well. We would not even consider using the low cost head bolts on any engine we build, ARP only in our engine room. For those building a stock or very mild street rod, the low cost head bolts will suffice. The cross reference number for the ARP heads bolts is 134-3601 We offer them in our other listings, and strongly recommend using them.
