Both are great heads and flow about the same....AFR's are more$$ and TFS have more portability. I love mine. I think that any hi-temp paint will work ok. Engine cleaner is a beotch though....not sure about that. You might want to look into a rebuild first though...120K is risky with that power, and with that mileage, you will be lucky to hit 285-290 rwhp. Your tolerances are probably off, and your rings and bearigs are prolly worn also.....better safe than sorry.
