Alright..so ive decided to go with Patriot heads (since they are the friendlyest for my budget)..
now..should I get
LS6 Style Heads
or
5.3/LS1 Heads
I am not running F/I..this is going to be an N/A setup. Ill be on a stock short block and am looking for around 440 RWHP when its all said and done.
what about lift and CFM? I know that all depends on the cam...does anybody have any opinions on what would be a descent setup for me?
orrrr..does anyone have any ideas/experiences on decently priced head and cam packages that can maybe get me near the goal im looking for?
LS6 all the way, way better flow and doesnt screw your compression like the 5.3 does. I have the stage three's and i will never look back at the 5.3's again.
what kind of power increase did you see from the LS6 heads? are they from patriot?
I also went with a bigger cam but my increase was 35 rwhp with the Patriots and then when I built my other engine that is a 408 i went with the patriot heads stage 3 for the lq9 heads and that was 50 rwhp gain so i have always had good luck with Patriot Heads:burnout:Quote:

what are you setting at now rwhp? what cam are you running or thinking about running? heads we talked about Patriot Stage 2's, and intake?
right now all I have is a Lid (w/ free mod), ported TB, street tune...
im not looking something too lopey..maybe somewhere around 112 LSA
Texas Speed Pefromance, have my favorite camshafts, but just with camshaft and heads and headers on my orginal stock ls1 I went from 336.8 rwhp to a gain of 135.6 rwhp putting me at 471rwhp. So, to awnser your question I went TSP Magic stick 4 camshaft, Patriot Stage 2 Heads, and QTP Longtube Headers and I easily obtained your goal Rwhp goal.:coffee:
:)....im liking thisQuote:

yep those are the exact ones...
yeah man use the ls6 heads. I did but went with a much smaller cam and now I regret it but I still love it!
LS6 is the way to go....:snowboard:
but aren't those stage III heads that you have meant for bigger engines? Like 383, 402, 408?
At least that's what I was reading.. and that stage II or 2.5 or good for the ls1's?
right... stage III for bigger cubes and stage II or 2.5 for ls1's.
