I was wondering if anyone was running them or knows anything about their quality, I was planning on running ferrea valves but these seem to be cheaper and the manely rods are good quality. I will have them on B18C stock bore with 9cr running about 20psi, thanks

 

The stems on the manley valves are a lil larger than the valve guides...you have to mill out some material on the inside of the valve guides.

 

I'm also curious myself for any info on these valves, and places to purchase them...My "domestic" machinist loves them and told me to get some if/when I do new valves.

ok so i would have to mill them but are they as good a quailty as the fearea ones? also where would i be able to buy some, i just heard they were cheaper and pretty good.

 

try http://www.manleyperformance.com for info... I had a nice site to puchase them but I cant seem to find it again
