That pretty much sums it up. Area under the curve is a huge thing in power outputs and getting a car down the track. Darryl knows his stuff as he has a pretty good background behind him w/ his degree and then becoming a teacher at SAM IIRC...Chris 96 WS6 said:The absolute best head in terms of flow numbers would be an AFR LT4 casting.
As for the best ported stock LT1 head i would have to say my friend Daryl at RPM is as good with the stock head as anybody else out there, and is better priced than most. His flowbench numbers are very conservative, so if you shop just based on peak numbers you might not be that impressed, but peak flow is not gospel with regard to cylinder heads.
Peak flow is like peak dyno HP......all the pretty numbers are worthless if the car doesn't run the ETs
IIRC, the main thing that makes LS1 heads superior to LT1 heads besides the increased volume is the 18* (I think that's what it is) design vs. the LT1's traditional SBC 23* setup.1970judge said:Im pretty deep in lt1 tech but one thing i never got is what makes ls1 heads so superior to ours? Amd why do ours flow like crap?
I'm no head expert and know nothing about an LS1 but I believe I read that it's the cathedral shaped intake port plus the 18*. The port shape was happened upon by accident.1970judge said:Im pretty deep in lt1 tech but one thing i never got is what makes ls1 heads so superior to ours? Amd why do ours flow like crap?
