Skyhunter, I've got a nice sharp carbide burr I can loan you!

I contacted ARP and told them what the FoMoCo bolts sizes were originally, and they emailed me these part numbers for their replacements.

HAP4.300-5  7/16 -14 x 4.300"
HAP4.060-5  7/16 -14 x 4.060"
HAP2.180-5  7/16 -14 x 2.180"
Washers APW1316
I contacted them today and will get them Thursday, which is great.

Just before I called them. I called Mummert for the 3rd time.  I called him on the 1st (said he had bolts in stock but no washers and would call ARP), called the 14th (said he still had no washers yet so I gave him my CC# and he said he would ship out just the bolts).  Again, after no CC charges for a week I called him again today and said he wrote all my info down but he said "I did not send them yet but I got some stuff from ARP Thursday so I can send them!!!".  Well lying and blowing me off for weeks was no bueno.  I asked him after calling and being told he would send them, What's the disconnect?  He just said "It is what it is, you want them?"  I wish I could have reached through the phone.

I will probably grind off his name from the intake and the valley pan cover while I got them off so I do not advertise him at car shows.  EABODs

You can go to any industrial hardware supply and get Socket Head bolts and hardened washers in whatever size you want, just make sure there grade 8 or higher .

Headbolts.com showed the kit in stock last night.  This morning I had email saying the order was cancelled and now I see it is out of stock.
As far as the lengths, you are correct.  There were no washers when I took it apart, so I guess I'll put it back together without washers. 
Using the 4.25" bolts on the outers without washers will be a lot better than the 4" bolts I took out.

But the bolts needed for the four long head bolts on the top outers are 7/16 -14 x 4.32" and the set in the ARP are 4.25".  Will it be long enough with the washer included?

Also just looked at headbolts.com and they are listing them as out of stock.

I'm also looking for a set of head bolts and I may have a work around for the ARP kit that is backordered.  Following DryLakesRacer's lead, I ordered chbs-1221 from headbolts.com which are in stock.  That is the ARP kit with all of the long bolts the same size.  Then I ordered ARP655-4250 from pitstopusa.com.  That kit has 5- 7/16-14 x 4.25" chromoly bolts that I plan to swap for the outside bolts on each head.  Seems like it should work.  I'll post again once I get them.  

I saw that listing, but they have been showing out of stock for the last month.

At this point I would buy them from ISIS or Putin and pay dearly for them.

I normally purchase the ARP studs, bolts, nuts, and washers we use from Headbolts.com since my son and I use them for our other racing engines and they usually have what we need and ship the following day. I used them for my 292 YBlock and received them in 4 days as they were in stock last week. Came ARP lube also an 1 extra washer for some reason. Not one of our normal responders/suppliers here but have good to us.
They were the set with 3 different lengths. It’s the one receipt. I can’t find. It was not the set for the early engine.
If I would have thought about it I would have bought the 4 outside as studs by length after checking the depth of the thread and shank section needed from ARP. It’s how I buy studs for my GMC 6’s.

Still waiting on a set of head bolts.

Called a supplier on March 1st, gave CC # but he said was out of washers and he was going to call ARP and get more and send them.

2 weeks later still no word.  Called him and asked about the order.  Got the old "umm, well, umm, did you place an order"????

Told him on the 14th "just send the bolts I will get my own washers! I need bolts!"  Hung up and called ARP for the washers and they gave me the part # and said Jegs was cheaper and faster.  Got them last Thursday.

Today, still no bolts, still no charge on my CC#, no calls no emails.  Sunday the 27th is the biggest car show of the year here.  Very nice one where they shut down the downtown.  You have to apply and then prepay if accepted. I would have to push the car there now!!!

I know it's not a big sale item for this guy, but I have bought an aluminum intake, one of his valley pan covers and other of his custom products in the past.  Why can't people just do a simple job.

Thanks Ted.  I will do just that.  I am waiting for a set of head bolts from John Mummert.  They are ARP.  Called him on the 1st.
