who to buy rhs heads from

Those times you are quoting are from member "Dusterdoug" and his RHS Headed Duster.
Brian's went a 6.95ish in the 1/8th in his HEAVY Duster which is about a 10.90ish or something close to that in the 1/4! Remember that was with a Non Purpose based Converter and FOOT BRAKING IT! Compression was 10:1 or so on PUMP FUEL! Would have been better for damn sure!

Ok, still kickin *** either way!
