HI Russ My very helpfull rover part guy,

Advised me as below, for roller rockers. I have bought the parts, but not fitted them yet. I can get them out and take photo’s if you like?
" Pushrods - Typically these need to be made to suit however the easiest way around this is to fit the Adjustable pushrods which allow the correct valve train geometry and lifter preload to be achieved £134.95. It is important to set the rollers with a contact or strike so that the roller is central to the valve tip midway through the valve travel. This minimises side thrust and consequently reduces friction = less wear and more power"
As an aside, I really got lucky. After pretty much finally deciding that I would have to rebuild the old smoker P6 RV8 I bough as a "setup" engine, a tiny local paper add turned this up - Brand new block, built and blueprinted by a reputable local engine builder years ago for a stillborn racing car project. Never been started, still with assembly lube inside. Oversize valves, gas flowed heads, roller rockers, dry sump, even came with some of the dry sump setup bits. Unfortunately somebody had pinched the lifters and pushrods, but it did came at the right price.
An invoice with the engine shows a huffacker intake manifold that was included cost 127 UKP from RPI in 1995! I plan to run quad downdrafts on the real engine though
I had already ordered all the rebuild parts I needed for the older engine (pistons, rings bearings etc) at more cost than I paid for this, and Paul was okay with me cancelling that order and instead just buying a milder cam than that was in this engine, plus the lifters gaskets etc.
Cheers
