I'm running the HP292's not degreed and have had good results for 9+ years. When I first installed them, I still had stock heads and valve springs. I used the AFM cam retention tool to install them, so all I did was remove the valve covers. I didn't even have a spring compressor at the time. I removed the rockers by rotating the cam to the base circles and prying on the rocker to the side. Then I bled down lifters in a vise before reinstalling them. It took me about 3-4 hours to swap them out. Without any other changes and a retune I picked up 91 whp. I limited my RPM's to 6250 on the stock springs. I'm running patriot stage 2 heads now but I still haven't degreed the cams.
I know it's always better to degree cams and some need to be, but I felt comfortable with my pistons being fly cut not to worry about PTV contact. The duration is a little wide but the lift is only 531. The first time I installed them it was 10 years ago and I was out of money in my budget. I have also degreed cams in other engine builds since then and feel comfortable doing them now. I'd like to degree them in the future and maybe port my TFS intake at the same time. I'm thinking about looking into extrude honed for the intake?
