862s vs 243s... Now that a lot of guys are switching to 6.0/6.2L setups with L92/LS3, 243 (and identical truck 799) heads are getting easier to find.
I have a stock 5.3 (mods in signature) and I am thinking about switching to 243s.
What kind of power gains do you think I would make by switching from the stock truck heads to the little better flowing 243s (milled to compensate for combustion chamber and compression drop to stay at 9.5:1)
