i've driven a ZO6, only up to 171 MPH on a slight curve, i've had a crate LS7 on the floor of my shop but yesterday i finally had a chance to see what i've been waiting for. a customer dropped off a set of LS7 heads & intake for me to port. it's not hard to see why those things make decent jam. the exhaust port itself is not too far off some of the 15°/18° inline valve & splayed valve Super Stock/Competition Eliminator stuff i've done. i told the guy not to expect any big gains, that i would do what i could. i think the valve angle is around 12° stock. nice stuff.

Ryan, the intakes only need to be touched up slightly. The exhaust side is where most of the work gets done on the LS7 heads. Send pics.

i can't be too long or the auto log out hits. never had a chance to post any pics Jeff, customers grabbed them as soon as i was done. thought you guys might find this interesting. they dynoed it today. stock short block untouched except for a cam change, .242° INT. .247° EXH. @ .050", little more C/R 11.2:1, true full length headers, my porting & they dialed in the fuel mapping. pump gas. best TQ. was 585 @ 5500 RPM, H.P. was 660 @ 6800 & 6900 RPM. average power between 4000-7000 was 579, average TQ. betwwen the same range was 552. Superflow 902. pretty impressive for the minimal work. good piece of enginering IMO.

as a side note: they also dynoed this thing before the heads came off. with the same full length headers as above it made 512 H.P.
