Yes there was no liquid coming out from the valves, i sprayed WD40 through the exhaust and intake hoes and nothing leaked through. However in the picture you can see, we identified that there was that groove/Chip near the valve.
SO can i clean the head and valves etc with a toothbrush and Wd40 or carb cleaner? Or do i need a special cleaner?
DO i need that specific bolt from the dealers or can i get the same from a local hardwear store? If not, can you direct me to a site where i can buy the bolts i need.
Do i need new dowels? if so how many?

Searching for bolts atm, any help welcome
Bare in mind guys, i have never worked on a engine before, let alone a Yamaha Raptor 660 Quad Bike. This is a massive learning curb and with the help of this forum I have got this far.
I'm not sure how that chip(s) got by the valve unless someone replaced the seats and it happened. As long as it wont leak or have sharp edges it's OK. If it's sharp, round it some with sand paper or rotary tool.
Yes, you can clean the head with any solvent or WD40. I would use a degreaser after the WD40 on the gasket surface so it's not slippery. If you have something "perfectly flat" like a granite counter top or thick glass, you can check the head for warpage. Look for the instructions and specs in your manual.
YES, dowels need to be there. I don't know how many there are, but they can be reused. I would think at least 2. If damaged, try a cycle shop.
The 4 main cylinder bolts with hex heads should be replaced every rebuild but most people don't do that. So you can reuse them, I like to retorque them the next day. The smaller Allen head bolts can be replaced with quality replacement from a cycle shop or local distributer.
Just think of yourself in a motorcycle repair class. We all have to get our hands dirty to learn and you're doing a fine job so far. You never thought you would get those head bolts out, but a little perseverance and bad words and they are out. GOOD JOB!!
The assembly will get serious, so while waiting on parts, it's best to read ahead in the manual so you understand the next steps.
