[ROVERNET - UK] Help!!!! Rover V8 Motor Question

[Kent Kinard]

Hi Geff,
I will have to dig up some numbers on the plugs.  The plug 
reach differs on the pre-'76 and post-'75 heads and using 
plugs with the wrong reach can produce hot spots or 
fouling in the combustion process.  Exact heat range may 
depend on other tuning details, but I can give you a place 
to start.

"Chevy valves and springs" is not enough information to 
allow us to duplicate the installation.
I have a set of heads with Volkswagen valves, but they are 
extensively modified and only my machinist knows how or 
how much (although I know the valve heads were reduced in 
diameter).  Stem length is critical on Rover V8's and I 
expect the stems on the Chevy valves were (or should have 
been) ground down to produce correct geometry in the valve 
train.  There are no Chevy V8 valves that are a direct 
replacement for Rover valves and far as I know.  Although 
215 Buick valves are a direct replacement for early Rover 
valves, the material is not compatible with the use of 
unleaded fuel.  SD1 valves and valve seats are slightly 
larger than early Rover valves and seats and do well with 
unleaded fuel.  Older Rover heads should have their seats 
and valves replaced when using unleaded.

Roverly,
Kent K.
