5.3 Heads
Hey Everyone.
Ive got a set of 716 casting 5.3L w/ a bowl blend done on them.
Trying to determine if i should use these heads or go for some 241 castings.
Here's my motor spec's:
'99 LS1 shortblock
TR230 cam
Stainlessworks LT headers
LS6 intake
Im trying to make the car a good cruiser, make about 380+ Rwhp, and get some decent fuel milage.
Ive got the 5.3 heads now, is it worth selling them to go for 241 castings? I really dont want to buy any CNC heads, or LS6 heads.
If it means ill make 380rwhp w/ the 5.3l and 385 w/ the 241 heads i wont bother, but if its a 10+ rwhp difference, then i might as well
All help greatly appreciated.

I'd use the 5.3 heads, have them milled as much as you can get away with before having to flycut ($50), and cut for 2.00 / 1.55 valves ($24). That way you can use the stock valves out of a set of LS1 heads that you could probably get for $25-50 depending on your shopping ability. That'll let you work with what you have and work well on a budget.

If its only going to cost me $100 to have the bigger valves in my 5.3L heads and i would have higher compression so more tq. then id definately be willing
