C15 6nz Inframe time

[Rhase trans]

This is the first I've heard of the steel liners. I would definitely be interested in trying a set. As far as the head from Portland, I'll run it over a head from cat hands down. I got one on my personal truck going on 2 1/2 years, {portion of post removed}. Not a single issue with it. Another on tuned 6nz, never had it on the dyno but it runs very well. I just did a b model with his head. It looks like a nice piece, time will tell. I will be trying one of his heads on my x15 when the time comes unless I see reason not to. Others may have had different experience with them. Mine have been good. The man went 300 miles out his way to bring me the b model head last month after I ordered it at 10 pm. He was at my shop at 8 pm the next evening with a ready to go head and no shipping charges to boot. Now everyone has they're own experiences with products. But remember you don't know the workmanship of the mechanic unless you did the work yourself. You will always here how bad something was if there's a problem with it a million times but rarely will you here how good something is if it doesn't fail. My two cents with my own experiences.
