So is L92 the way to go?
What is the least expensive cylinder head setup that flows the most cfm?
I saw that l92 heads ported will flow in the 370 cfm fully assembled for around 1800.00
Are there better heads out there for the price?
Also who makes makes the 6 bolt per cylinder heads because down the road I want to run a LSX block?

Stock GM Heads typically cost:
$380 pr
16x $15 each for Valves $240
Double Spring Kit $275
Total: $900
PRC CNC Ported L92 Heads
$1099 with stock springs
$1349 with prc doubles
For the power gains the prc head is definately worth the little bit of extra $$ over the stock gm castings.

L92 heads are a great pickup for something like a stroker engine. On our 403 combo L92's made right under 550 in a 6speed Vette. They flow excellent numbers out of the box, but as mentioned above, make sure your air pump can pump enough for those heads.

I know I dont have the whole picture, but what is the TQ like from 3000 to 4100 RPMs?
Is something like this going to take off slow, then kick in at 4200 up to 6400 rpms?
TIA
