Re: [Amc-list] 195.6 OHV head bolt dimensions

[Frank Swygert <farna@xxxxxxx>]

Tom, did you just measure the bolt from out of the valve cover, the one that holds the intake down? 5" below the head sounds right for those, but I think the ones under the valve cover are the short ones (3-3/4" below head to end) I mentioned in my previous post. I have a couple head bolts here that I'm 90% sure came from a 196, under the valve cover, but I might be mistaken. I'm 99% sure there are two different lengths though. I was thinking the longer ones were at least 4-1/2"-4-3/4" but wasn't sure, 5" sounds about right for them (5" from bottom of head to end, would be roughly 5-1/2" overall from end to end -- the short ones would be about 4-1/4" total). 

7/16"x14 tpi is standard US coarse threads -- easy to find! Wrench size really doesn't matter, and washers can be used instead of the oversize shoulders. 
(just here for Dave's info and your comment if you disagree).
