So I've been doing some research on ls1tech/AFR's
website re: the possibility of swapping my crappy
98 LS1 heads for a set of AFR 210 CC's or Texas
Speed ported LS6 heads for a little less money.

Of course, I would also upgrade my push rods to chromoly hardened and also do LS6 valve springs. This would be for longevity as I'm a big fan of revving past 6 grand.
The thing is that the 98 - 2000 LS1's came with a bigger cam than 01-02.
98-00 LS1 dur 202/210 lift .496/.496 w\ 116LSA
01-02 LS1 dur 198/197 lift .478/.478 w\ 115LSA
I've heard that you can get 40-50 rwhp out of a good set of heads alone on an LS. I don't want a choppy annoying cam and the associated tuning issues, poor fuel economy etc that comes along with that package. I've done almost all of the bolt on's and I'm thinking that head flow is my next restriction. Plus heads look to be reasonable for me and a friend to install ourselves.
Some good heads and I should be well over 350 rwhp and around 400 rwtq on a real dyno at our altitude.Plenty of power for me.

^^417 rwhp on a dynojet but still! *Also on an IRS GTO
so more drive train loss than the solid rear in my F Body.
What do you think?
