Thanks for the advise fellas, that build will be a while away while i cut the rust out of the old girl no point building an engine till i can put it in the darn thing... 

There is some in the top of the lh a pillar which i wont know the extent of until th bog from a previous cover up comes off and a bit on top of the wiper plenum which i can easily get the section for i checked inside the grille you mentioned aand would you believe not a bloody spot of rust and about half a dozen leaves

And probably worse would be this in the rh c pillar

After a rather short investigation i have found the following rust in my xf is this beyond repair? 

I dont have a setup in mind i will research that at a later date its just i have 2 running engines and just at intend to use the one with the less ideal head as the one to get it registered and driving while i do the nessicary work and preparation to the second. But the basic idea will be a camtech CT142 517 and nessicary work to match or perhaps a custom turbo efi setup unsure yet just want something torquey and yet plenty of punch on the open road. 

After some info. Looking at building a solid street 4.1 carbie fed and curious as to the best cylinder head to use eg c1, c2 or other, i have a c1 casting and a c2 and intend larger valves and nessicary port work so with this in mind will it make any difference which i start with? Not after a specific power more just a very solid amount of torque. Any info would be appreciated as i cant seem to find a whole lot of info on the old bangers.
