Head Gains
I have a stock ls1. I put a ported throttle body ,ls6 intake B&B short tubes. ls7 coils and after market air filter no tune. I bought a nice set of used #1510 AFR 205 heads. I am wondering how much HP will I gain with heads and tune I know it will be more with a cam but on a budget. It should be around 80hp if I do cam and heads. But I was just thinking heads. I LIVE IN CALI SO THE RULES HEAR SUCK!!!

OK so I guess I am doing the cam too.So any cam #s that will work in California. Nothing to crazy,have to pass smog. I don't care about top end squeeze numbers they are just for talk,Need strong mids and torque that's where we really drive.something that pulls hard when coming out of a corner

Long story short between the two, the 224/224r is a good one if the car will remain naturally aspired. The 228 exhaust is meant for forced induction to aid in getting the gases out fast. The 224/224 is a safer bet for emissions and will maintain better low end characteristics. I am going with the 224/228r because an a&a supercharger is a high priority for me in the future. Ive researched tons and tons about this build and from every tuner Ive talked to, these are basically the best you can do with Cali restrictions.

224/224 .581/.581
224.228 .581/.588
Both come in a variety of lsa's, but 114 is the one you want for emissions. Not sure exactly what the operating range is, but I have seen dynos of this cam make great low end increases as well as high end and bringing the rpm up into the 6500 range. (My 99 with stock cam fell off at 5300 rpm to give a reference). I know the increases are positive across the board.

totally agree with the 224/228 either 114+2 or even 115+3 for a little
More stealth.Tony Mamo developed the 224/228 came specially for the
AFR 205s when he designed these heads. PM him here on the forum
He's a great guy to work with and he did deveop the first aftermarket
Cylinder Heads for the LS1 and every cathedral head for AFR thereafter
205,225, then 210, 230, & 245s. The extra 4 on exhaust will help since
You do not have LTs. Should add another 30+rwhp and give wicked crisp
Throttle response from 2500 rpm and pull all the way to 6500 rpm!

Best to go with the GM .051" MLS. And clean the piston tops. Timing is going to have to be real conservative with the stock cam or you will get detonation. You can't rely on the ECU helping you. It needs to see the detonation in order to apply knock retard, but by then, detonation has already happened.

Latest GM High Tech & Performance Mag (May) put AFR heads
With cam 227/230 .582 with 114 LSA on a 2003 Z06 made
444 horse and 405 torque on a Land and Sea Dyno
Stingier then a Dyno Jet I believe. A unported new Fast 92
and LS2 90 made 15 horses more than the LS6 manifold
