GutlessSupreme Posted October 10, 2006 Report Share Posted October 10, 2006 Ok, first = TGP, second = TSTE.. I can't remember if I've read anything on this before, but not all turbo heads were created equal... the TGP heads look like a cross between the TSTE heads and the heads on my Cutlass (unsure of casting number). They have the sharp divider between the valves like the Cutlass (as opposed to smooth/rounded off on the STE), but have a much more defined plug entry hole like the STE near the top of the intake valve (whereas I believe the Cutlass heads are nearly smooth and level with the top of the hole instead of concaved inward). Just something that seemed interesting to me as I was comparing my chinsey port job I tried on the TGP heads (before I found a crack) to my rebuilt unported (at the time) STE heads...
