202 heads are double hump and the regular small block has single hump.
take them to a machine shop
Very hard to tell without pulling a head and measuring the stroke, but there are some signs that might help. If the factory intake has an oil filler tube and there are no bolt holes in the ends of the heads, it's probably a 327.
You will need an OBD2 code reader. They can be found at most auto parts stores. It will tell you why it set off the engine light, and usually allow you to clear the fault codes.
#1 is the cylinder closest to the front of the engine (where the belt is). On a V engine that is harder to tell unless you can see both heads at the same time.
The 1975 L48 Corvette engine was the "base" engine and never was offered with aluminum heads or a 4-bolt main block from the factory. The L82, offered in 1975 had 4-bolt mains but still only had cast iron heads.
Your question is a little vague, so im assuming you're asking which is better between 350 and 305 heads. Many people will tell you it doesnt matter. I think if you have a 350 engine then you should use 350 heads. the 305 heads will have higher compression, which will make the car louder, and somewhat faster, however, if you use 305 heads on a 350 engine then you should use a high octane fuel, so it will be better on your engine. Only use 305 heads if you know what your doing. if not you should probably stick with 350 heads. i hope that answered your question.
No way to tell without taking it apart.
Yes there is. I would tell you what thay are, But I need to know the year and what size engine.
It is not advised that you stop taking your clozapine without your doctor's approval. A urinalysis can tell if you have been taking your medication by the levels that are present in your system.
You cannot tell by looking at it. For this reason it must be changed at a set time period of miles or years. Without knowing the make, model, engine, & year I cannot tell you when it should be changed. Warning: If the engine is an interference engine and the belt breaks you will have internal engine damage.
It could be as simple as a vacuum leak but without knowing what year, make, model and engine it is hard to tell you what it may be.
you will know that you have ulcer without consulting a doctor by feeling pain before and after taking in solid or liquid foods.
