This is the set up I ran in my ’02 Vette (LS1) for about 3,000 miles. I wanted good low and mid-range power. Worked great and increased my stock rear wheel horse power up about 60 hp. Drivability is not affected at all with this rather mild modification combo and it passes smog fast and very clean.
Heads: GM 1256-4243-B (243) LS6 with 918 upgraded springs
Cam: Synergy custom grind 220/220/114 +2 .568/.568
I recently went a bit more aggressive with AFR heads and a little taller cam. I used the push-rods off these heads otherwise everything is still there. Great setup and a cost effective way for a LS1 to gain measurable hp and yet still be a sleeper. The dyno sheet in the photo is from the original installer and shows 378 rwhp with this setup. I never took a base line dyno but most stock LS1’s are probably around 315 rwhp.
Let me know if you have any questions, these puppies aren’t going to do me any good sitting in my garage.
$500 for both ($450 heads & $150 heads if separate) - plus 50 bucks to ship ‘em.

Package still available.
Lots of folks are asking about just the cam or just the heads lots of responses. Thanks. I'll wait through Sunday to see if anyone wants the package then start responding to separating them out and selling individually.
