Bruno wrote about these; "...the diameter and thread pitch is 5/8-11. I went to the bolt shop and bought 4- 5/8-11 x 3/4" stainless steel bolts. The cost was $7.29. A person could get off quite a bit cheaper if they could find just a regualr grade 5 in the same configuration and either paint them or leave them *****. I would assume this could have been for $2-$3 if I went that route. I used ARP thread sealant on the threads. I used the same sealer(reccomended by ARP) to install my rocker studs in the heads. So I am assuming it will hold up. If not Loctite makes a thread sealant used in boiler and hydraulic applications labeled 545. This stuff is much thinner and is very similiar to the consistency of their thread locker product. I went with the ARP sealant b/c the thread pitch is so coarse on these bolts I was worried it wouldnt seal well.
The only thing I would say to watch out for when doing this is to not crank down on the bolts with a lot of torque. The location of the thermactor port is over to the side of the head and isnt very thick there. It looks as though a person could break the head very easily and open up a can worms. I tightened mine down with an end wrench. The head was a 15/16". If I had to guess at how much torque I put them under I would say 45-50 ftlbs .
Good luck! The bolt size is a little uncommon as far as the thread pitch goes. I have a fastener supplier that I do a lot business with and they had them in stock. I considered using a set ***** with the same dimensions , but , the machine supplier only had them in 3-1/2" lengths. I used a set of calipers to measure the depth of the thermactor port before I explored my options. I did this so I wasnt limited to one length and it increased the chances of finding something that would work. The port depth measured out to be just a little longer than 1-1/2" maybe 1-5/8". I would assume a 1-1/2" length would work as well.
351 and 302 heads are reversible. In other words there is no left or right head .So there is thermactor port on both ends of each head as well as threaded holes for the accesories on both ends.
I ran the bolts in and out while blowing the hole out with the compressor and blow gun. Then wiped the doo doo off of the bolt before applying the thread sealer..."
