I've got the same heads, and I got 15-20 hp and 20-35 lb-ft of torque. My peak hp is off though becasue I have a little cam (210 intake). I'm sure it will pick up once I get a bigger cam in there.

Springs are rated to .600 lift. Here is a link to the same springs on Summit: http://store.summitracing.com/partde...5&autoview=sku
Yes, the pushrods are shortened to match the mill job.
I'll open one and post up some pics later today.

what CR were you running?
These ones are cut .030"

I compared my dyno graphs before and after and it was funny because the gains started out great in the low end, but I peaked and stayed flat at 316 hp at 5200 rpm. Before the heads I peaked at 310 hp around 5900 rpm. So you can see that the heads are working, I just needed more cam to get the rest of the top end potential out of these heads.
