AFR 210 LT4 heads, lightly massaged
Pre Eliminator AFR 210 LT heads. LT4 style with a 75cc chamber. Comes with PAC Racing Spring 1.550" OD Roller Dual Valve Spring, .710" maximum lift.
These heads have been ported on the intake side and flow better than factory. AFR advertised their flow numbers on these heads at 275/220 at .600 on a 4.125 test fixture and a pipe on the exhaust. As you can see from the attached pictures these heads flowed 280/190 at .600 on a 4.060 test fixture and no pipe. These heads aren't fully cleaned and should have better numbers when the ports are bare. It's a bit over on the intake than factory CNCd, and when you add 20 or so to the exhaust for a pipe it is right on as it should be, and maybe a bit more.
These heads made 1400hp in a big turbo 383 LT in my friends race Camaro. He is going with a big block so these have to go. Flowed and checked out and they are in great shape. These heads are a must have for a boosted car. And quite a bit cheaper than any of AFRs new heads. You can even have these ported for more flow if that's your plan. Current AFR heads that flow like these are priced at $2200.
$1200 shipped in the lower 48. Comes with a set of center bolt valve cover adapters like these. http://www.summitracing.com/parts/nal-24502540
Thanks,

Re: AFR 210 LT4 heads, lightly massaged
Price drop.... need these to go. Can do partial trade on new high volume oil pump, new 255lph Walbro, quality new injectors, ...Other ideas I will listen to but need to based on an Impala SS not an Fbody. Thank you
