Building an engine around a cam is not a good idea. Building an engine around a junk grind is worse. Reverse split cams are inferior to the traditional splits. Buy the best heads you can afford, and cam accordingly.

Not worth either the time or the money. By the time you get a valve job, factor in new valve costs and then all the machine work, you could have had a stock set of 243s that would work MUCH better, or just shy of a budget ported stock casting like the PRC or Livernois heads that would be better yet. Bigger valves with a GOOD valve job, and a mill would yield little power with the 241s. Certainly less than the alternatives.

i have a ls1 book and it has all the heads and numbers , and the best , where does it say about 243 is the best head and rwhp is not the hp the engine is putting out , you got loses at the rear wheel if you getting 360 hp at the rear you got over 400hp at the motor , where can you get heads that put over 400 hp at the motor for 550 bucks

silver- 1998 camaro ss
don't listen to mark 85 z, i have the same cam and a set of 5.3 liter heads and made 455 rwhp back in 2002, thats an old setup that still makes more power than most heads and cam cars out there today. 11.10's all day in a 6 speed on a 1.72 60' at 122mph is not bad. a better 60 and the car will run 10's on motor at stock weight fully loaded ss.
