Hi all, am trying to decide on a decent, but not overly priced set of high lift rockers for my min, as my standard rockers are worn out and also letting too much oil get up into the rocker cover.!

Anyone had any experience of this set from Jonspeed..?

Thanks!

There is no requirement for a special rocker cover for roller tip rockers (although some do nned tweeking).

Personally I'd buy roller tip ones from minipares or the like. Roller tip rockers greatly improve the life of valve guides.

The choice is yours, and as wolfie says on a Turbo motor,

If the head is ported to flow at the increased lift given, then there's no reason not to use them.
The A-series prefers high lift short duration rather than long duration short lift anyway.

Thanks guys, it was more whether to go for non roller tip like the set in the link, or pay the extra for the rollers. Think i'll be going with the latter *smiley*
