They would lower the compression ratio.....

They need to be post 98 heads as these have the extra casting sections with tapped holes to support the DIS packs.

According to my calcs, it would take it from 10:1 down to 8.36:1

Thats a big drop and would affect performance and economy

oh... those stupid things!
i'll have a look tonight or tomorrow (doubt it'll have them tbh)
why not just not both with the little torx bolts? the seemed like right little barstuards to pull off/out so dont imagine they would "NEED" them imo
