lm7 heads to new 5.3 799 benefits?

[beingblueeyes]

what would the power gain be by going to a set of 799 (milled down to keep stock CR) with the mods i have (link in sig)
would it be worth 600-700 total to do it (heads/machine work/valve springs/gaskets/head bolts/ls7 lifters because i was there)

Yes it'd be worth it.

[o2camaross]

Aren't they the same as 243's?

[Frenchy]

Yep

[beingblueeyes]

thanks Frenchy, ill put them on my wish list then

not worth it, youd have to mill them to at lease .030 keep the stock compression ratio of the 5.3.. yes they do flow alittle better but for a NA setup id find another route, now forced induction yeah it would be worth it.
