Lol, no man, its just my DD Ls1 that has a stock bottom end somebody else asked about it earlier, thats where that comment came from.steve316 wrote: ↑Sun Oct 15, 2017 12:01 pm What ever head you choose; I would not run them on a stock short block.Rods and pistons would have to be up graded at least. As far as witch head to run; I would vote for the ls3 because of air flow and the rocker arms you have. Ti valves will let your springs last 3 times longer. This is your budget so its your call, but if it comes a part it will not matter witch heads you have on, they most likely be scrap.Good luck Steve
The 408 rotating assembly is callies compstar crank/rods and wiseco pistons. This isnt a super budget build, im just not ready to lay out $4000 for heads for this build.
