I absolutely LOVED my Torquer V.2. Great power all the way to 6500, torque was a nice level line, and I barely noticed it driving around town.
Heads...I'm a fan of PRC. They're cheaper than AFR or Trickflow, but still have some nice flow numbers. I had Stage 2.5 5.3L Heads milled to 59cc chambers with my Torquer and stock bottom end. I now have their 237cc runner Custom Cast Heads w/ 62cc chambers on my 427 LS3.
I agree and disagree with you on this one.
For a stock bottom end, naturally aspirated LS1, you're not going to gain much from a custom grind. Almost every combination of duration, lift, and LSA has already been massed produced by so many companies out there.
For a custom built stroker motor, yes go custom grind. It will get you exactly what you want for your style of driving, especially when you add Nitrous or FI.
