Well… more time than I had thought
So before ordering this kit, I asked an associate if there was anything else that I should go ahead and do while I was already “down that far” he told me this kit did NOT require you to remove heads. Maybe that’s the case if you’re just doing camshaft but if I was just trying to do camshaft, I wouldn’t have purchased the whole masters kit… The lifters and all that, DOES require the heads to be removed.. So a little misleading info but I’m figuring it out. Taking a lot longer than i anticipated. Items seem to be high quality, and packaged well. Nothing messed up or any flaws at all.

Dave’s Challenger Stage 2 HTR Cams
I installed stage 2 HRT comp cams 273/279. The install wasn’t bad and everything you needed was provided. The cam kit was shipped and arrived fast and on time. I purchased JBA long tube headers, looking for options on mid pipe, before I send it out for tune & dyno. Great product and can’t wait for dyno results.
