Re: Jag IRS info?

The Jag IRS of choice for the narrow Ford Pop (sit up and beg) is an LSD version but using S type drive shafts it all remains narrow this way 8-) they are very strong and will take big block V8 abuse :wink: .... up to a point however then the drive-shafts become the weakness

Re: Rocker Gear lubrication

<r>Some builders fit restrictors to limit rocker oiling this increases oiling elsewhere also, often carried out with roller rockers etc and no not standard, unless its been fitted with hollow push-rods the single front port on each bank to cyl head is the only oil supply to rocker gear <E>8-)</E></r>

Re: Rover V8 cylinder head porting advice.

Using the Real-Steel larger 41.5mm inlet valve I managed to increase the valve seat insert by 4mm+ just be careful when pushing things I used engineers dye to keep things in check and not break into the increased valve sizes seats future area
