Deck flatness question

[chiodo]

Hows it going guys I have a 1970 Buick GS 455 Cali with 38000 miles on it (sat for 30yrs) and im doing a full frame off resto on it. With the frame and suspension complete im moving onto the engine block and my question is with deck flatness
I own a straight edge and as im working the the feeler guage across im able to fit .002 under straight edge on the number two and three cyinder wall am i good wit a composit gasket?

It looks like up to .004" is acceptable in a 4 cylinder or V8 iron pushrod engine.

One thing to keep in mind when doing the engine & something MANY forget about. IF you deck the block, especially on the left side where the engine code/ID are located, if this is a matching #'s engine that identification will be ground off. Now there's NO way to prove that engine you have, if #'s matching, came with the car. Now the value will most definitely be less. Something to keep in mind.
Just my thought on the subject.

Everything is good im not planning on decking it I want this thing original as much as possible. The only thing I need to replace is the timing cover right now

You might be able to answer a question I posted earlier since you have a california car, if it was built in Fremont. Check my post regarding engine numbers. I am curious to know the code stamped on the block near cylinders 1 and 3 on a california car. Might be same as non-california just not sure.
