Not Ranked
Ok guys, here's what I found:
Heads - other than the "2" on the upper rear corner of the head outside the valve cover, the only other numbers I can see (the engine is still in the car) are inside the valve cover in the rocker arm area. Once I took the valve cover off, I found sort of an oblong raised area with the numbers "2H30" inside it. I also saw a circle with the numbers 81357 in it. since the numbers are arranged around the circle, there's no way to tell which number is the first in the sequence. I started with 8 for no reason other than I had to start somewhere. Looking at Autoxmike's post, I don't think I have the right numbers for the heads, as the numbers and format don't seem to match anything. Where else should I look for numbers? Where on the head are the numbers I need?
Block - After removing the starter, I found two lines of numbers. The top line reads "D2AE-CA". Under that it says on a seperate line "2HI" or "2H1". I can't tell if the last character is the letter I or the number one.
What have I got here, guys? Are the heads and block a matched set as delivered from the factory? Please tell me everything you know, no matter how trivial, about this setup. Are the heads closed or open shamber? Is the block 2 or 4 bolt main? If the block contains it's original equipment pistons (which I suspect it does), what is the approximate compression ratio with these heads? What year and model did these heads and block come from? Is there anyting in particular good or bad about the block or heads? Are either of them considered to be desireable for any reason? Any and all info is greatly appreciated!
