Rs turbo head the same as any other 1.6 cvh head?

I think the heads are interchangeable but rs turbo valves are different and obviously the cam. Then again does the efi head have different shaped inlet ports??

I've found that life I needed.. It's HERE!!
IIRC MFi RS Turbo heads are unique due to the composition of the valves. But everything else is shared with non turbo MFi heads.
All 1.6 EFi heads are the same wether it be an XR3i, XR2i, FRST, 1.6i etc.

As Rick says any injection head will be fine, Phil is talking about heads with certain casting numbers having more meat and this is true, NMS have a nice collection of them for their serious CVH builds as they can be ported larger and fit very big valves.
S1 heads had sodium filled exhuast valves and S2's didnt.

I have a mfi turbo head, and Im thinking of building a head for my carbed escort.
So instead of taking my carbed one of the road whilst the head is built, just using the turbo head chaging the cam for a n/a one
Any problems with doing this???

Id quite like to know because my engine has what i think is an MFi head, it was using the dizzy, and i want to run full EFi with a coilpack. But the MFi has been ported/polished.

I've just built an engine from about 3 that were lying around , we've ended up with rs turbo block , head . 1.6i crank , pistons , and camshaft . all new gaskets ,bearings etc etc (as new) . we've put 200 miles on it now and it has a slight misfire under load cut a long story short the camshaft wasn't the best . I've now compared all the cams I've got and not one of them seems to be the same ?? I'm guessing rs turbo head so i need an rs turbo cam ? it also on a carb ?

Rs1600i casting numbers
Hi just wondering if anyone had any information on casting numbers for rs1600i heads I've got a crosshatch cylinder head cast the 5/5/84 with a smaller number of 097832 with a 10 in a box further down to number 4 cylinder could this be an rs1600i it's also got the BRA Code any advice would be greatly appreciated

i have a similar crosshatch head ,has the BRA code and 097832 .can't see from my pics the 10 .date code is .-1-85 it was fully ported big valve head from vulcan engineering, so not sure if that was an rs1600i head originally or not.supposed to be the best heads as you can go larger on valves.not sure how true that is but from a rough measurement it looks like 43mm/38mm valves.
