Questions is my engine interfer or non-interfer type?

Your engine is an interference type of engine and there may be bent or damaged valves. It is hard to really estimate the damage with out performing a leak down test and then removing the cylinder head.

The way we do it is to pull the head and inspect it for damage. It's likely you will have just a few bent valves and you can have the head rebuilt and re-installed. This is probably the least expensive route and as long as the job is done properly, a very good fix.
