Default 70 L89 engine

I am restoring a 70 L89 and am hoping someone can tell me what;
type of head bolt design was used
Type of exhaust manifold bolts were used (such as all washer head or no washers for example or were they like the cast iron heads)
Type of head bolt design on the intake

I know exactly what was used on a normal BB with aluminum intake but not sure on an L89 with aluminum heads. Since this is the only 70 L89 known to exist, if any of you 69 owners can share close up photos of your survivor or perfectly restored L89 cars bolts look like it would be much appreciated.

You know the car well as it was in your L89 showcase. Now in the beginning stages of undergoing a complete and correct nut and bolt restoration.

Charlie has a really nice 69 L89 El Camino that I've seen a few times at the Pavs. Very nice guy too. If I'm not mistaken I think it's a low mile survivor? Haven't seen Charlie or the El Camino in over a year though with all the sillyness going on so my memory might be a little fuzzy.

----Heads, exhaust and intake have never been removed on the El Camino that I know of. It had some performance work done on it as the original owner was a marine hi perf engine builder, but none of the above were touched. It had a double pumper carb on it but the original carb came with it and I reinstalled it. I remember it also having a Mallory dizzy, but can't remember if I changed that back to the original or not....Bill S
