A few months ago I posted for billet heads being made, well the plan fell apart. I am still looking for a high compresion head for the l/c 90. Has anyone got any of these or know where a guy can get one. I know DRR was supposed to be coming out with them but I haven t heard if they were ever released. Any Info?

DRR has them out now for the W/C 90. Nice set up w/ a good chamber.

Morning all
are these heads the same as on our Apache F100 S, that is they are retained in position with 2 spring pins as well as the 4 cylinder studs ?

Nope, direct replacement to the DRR. Improves the performance greatly

sldhd700,
there will be a billet 2 pc l-c Hi-comp head available in a few weeks , this head is being designed for the drx 90 and 70 , it will have removable domes to adjust compression , it will also be liquid cooled in the head portion unlike the drr head . It will be made in America by DC. I will try to keep you posted.

Very nice,what cc did you end up with David ?
How much better is the flow rate(cooling) over stock ?
Like I siad before as long as the volume/rate exceeds the added temp for the comp.increase(on a stock motor) these things will be awesome.Either way they will work perfect for a ported cylinder.
