when fitting a bd15 exhaust and bd16 inlet cams
does the head need to be fitted?
if so in what way?
i've heard of lowered valve seats but dont know what that is
any details would be good to tell the guy thats doin it

 

if the guy thats doin it doesnt know, do yourself a favour and take to someone that does, cause it will only end in tears

 

The head needs to be modded for double valve springs.

Its the pistons that need to be modded for the cams.

 

pistons are done
the guy doin the head will know
but its so i can tell the guy who's head it is
as he's the 1 that'll be dealing with it
but as its the valve springs that need the mods it dont matter anyhow
as it'll be using reyland single springs
