Exclusive Report by Totally Speedway Ford 6cyl x-flow hi rise rocker cover

A Solution to a long term problem

A special report in the spot light section in the totally speedway mag found that Clarko’s Performance now has hi rise rocker covers to suit the Ford 250 / 4.1 cross flow 6 cyl alloy and cast iron cyclinder heads, rather then adding a spacer to the EFI styles or having to cut up 2 steel rocker covers, why not just have a purpose made cast aluminium hi rise rocker rocker to suit the application?

Benefits – these are made to clear the rolla rockers
- the cover is supplied with both pcv and breather cap grommets
- has cast in cone style breather shrouds

To prevent oil leaks from rocker cover spacers and the time it takes to cut up 2 tin rocker covers to avoid the issue of the rolla rockers hitting, lets face it this is really a 1 stop solution solver.

Never seen the Gympie track before it was a eye opener the track had a hill, hair pin, dipper and a dog leg never seen anything like it before
so this was a test,  Clarko and Luke had a ball, the car was set up for Brisbane speedway where the track gets real rutty , so we were chasing car set up at the new track. Due to rain on the last event the 30 30 was not run :-(
