In the interest of time, I think I'm just going to buy the complete RV head from EB. I'm not sure which cam to go with though. I'll need to call him to see how the two compare with the TRD cam that I already have. If the RV head with o/s valves doesn't give me enough power over what I've got, I'll chrome something and slap a few stickers on to make up for it.

I'm assuming that a new water pump is mandatory (still stock after all these miles) and a new oil pump may be a good idea. Headbolts don't cost much and after thinking about it and talking to a few people, I'm going to have to go with Kewlynx and skip the bored throttle body.

The motor won't be coming out completely. If that were the case, I'd fix the rear main seal. It leaks probably 2 drops per month and it drives me absolutely insane. I don't like leaks. My vehicles have to be 'just right'.
