But just 1 probly throw it across our shop at somebody... As for the question Is the bolts used to hold the head on a certain grade or a special bolt or can i go to the local true value and pick up a simple bulk bolt and put in the engine?

They were 7/16"-14X2&1/2" yellow zinc finish SAE j429 Grade 8 Hex Cap Screws Part#0115163. The was cost $0.896/each. All the head bolt holes were open into the water jacket in the three 8Ns I have rebuilt. If any hole looks blocked dig around and see if it is not just years of corrosion. I used a washer only because the head on the new bolt was not as big as the original and I liked the look. The washer from Fastenal was a 7/16" yellow zinc finish SAE Tru-Hardened flat washer Part# 1133816. The cost was $0.1912/each. I used Teflon paste seal on all bolts. I did not cut anything off any of the bolts. [Reply]  [No Email]

The OEM bolts are 7/16-14 x 2-3/8" long. A common 7/16-14 x 2-1/2" grade 8 cap screw will work just fine. Because it is slightly longer make sure it is used in one of the holes that go through into the water jacket. TOH This post was edited by TheOldHokie at 14:13:17 09/19/12. [Reply]  [No Email]
