Cylinder Heads, And the replacement thereof... Options

[Nozzle]

Well it looks like it's time for another rebuild on my engine and the current plan is to do a 2056 D-jet build based around the Raby 9590 cam kit from The Type IV Store. I wanted to get some prices for machine work to bring the heads up to snuff as they have well over 200K miles worth of heat cycles on them. So far it seems the costs range from $450 for a basic rebuild of the pair from Rimco to $2700 from The Type IV Store for their tasty 914 2.0 replacement RS+ heads. Needless to say that's quite a range and this is my first engine build so I'm unsure how to proceed.

Although I can stretch the budget for the RS heads, it just means the build will take much longer as that accounts for the lion's share of my original budget. So my question to the forum is, what would you do in my position and why?

Thanks,

John
