Rallye head swap

Still doiesnt mean it was done properly though. I know the car it came out of was a salvage one so not likely to have ca£e with any history.
Don't wanna go through all this effort and if it taps having to do it again.

Yep you can but you'll need a valve spring compressor and make sure they go back into the same place they came out of.
If you do that change the oil stem seals too for piece of mind.
