You would be better off leaving the spark plug tubes alone then breaking the seal they have into the head, as that could cause oil leakage into the spark plug well......messy.
Your pictures show that you are in great shape up top, under the valve covers.
I am leaning toward some shorter oil change intervals the next few oil changes, using a high quality synthetic oil and a oversized oil filter, like I am using.
Actually, the longer filter is easier to get on/off because you don't have to reach in under the exhaust manifold so far.
If you are not tight on cash, I am thinking that the Bosch Distance Plus filter (D3422)$10.72 plus shipping from Rockauto and $13.49 at Advance Auto Parts... might be a good choice, with the Fram Extended Guard (XG3600)$7.10 plus shipping from Rockauto, a 2nd choice.
These 2 filters have a synthetic media that has a higher dirt holding capacity than most other filters.
They both seemed to do well in river_rat's "from the bench" testing.
Hey itslimjim, still deciding the best route unfortunately, no worries id rather be on the spot. Thanks wiswind, for oil filter i dont care the price whatevers best, sounds like the Bosch is what i should do. I dont particularly like fram, i am not sure why, even though ive used it many times in the past. Yea im gonna need to scrub hat a little better around the cylinders, being oh so careful not to put pressure on them. I dont know im in a mental rut of the best plan of attack on this. That would most likely be because ive never done it. We'll see, ill update if i have an epiphany, otherwise im just following all yall's advice.
