Rv8 top hat advice

[ianstaffordshire]

Hello looking for a bit of guidance here, today I stripped down the 4.6 gems engine I brought to rebuild and fit in my tvr wedge eventually I was intending on fitting top hat liners as I read they can slip the old ones however now it's in bits it doesn't have liners fitted so is there any benefit from fitting them I intend to up the compression to 10.5 to 11:1 and fit a fast road cam it already is running canems ignition with slightly larger injectors.
What hp should it realise anything over 250 would be nice.

That would be extraordinary - are you sure about that? It seems more likely that you just aren't noticing the joint between the iron liners and the iron block.

Just googled it all 4.6 engines have liners.
