Help identifying pistons and cylinder heads
Have this 360 torn down and have a few questions.
Wondering if the pistons are stock, or stock replacements at .030 over. I ask because they all have the stamping "30" on them as pictured. I didnt get a chance to clean up the carbon in the cylinders, but managed to get a 4.02 reading on the one cylinder I measured with cheap digital calipers digging into a good layer of carbon at the top. Could these very well be replacements? They are over .100" in the hole still.
The cylinder heads are definitely small valve 1.88/1.60 heads, but im wondering what heads they are- none of the numbers on them seem to be numbers ive ever seen i.e. 596, 308, 302, etc. Based on the attached pictures, what do you guys make them out to be? I ask so I can look up info on them i.e. possible porting templates or flow
Last but not least, wondering if the valve spring and retainer appear factory? This engine has a very mild cam in it from what I am told, and how it sounded, but I haven't gotten the balancer off yet to get the timing cover and cam out. Wondering if the picture is telling as to whether they appear to be factory or aftermarket valvetrain parts.
Thanks!
