Ok guy's, we are having a one week sale on all cylinder heads from ET Performance. This sale will last from September 27 till end of business October 1st, 2004. It will include all stages of LS1, LS6, 5.3's, 6.0's and LT1's. This company has a great product and they are also a sponsor on this site. We have some heads in stock ready to ship, give us a call for pricing and availabilty on the heads that you are looking for. Let's see what we can do.

BTW, I will be posting dyno numbers for several different combo's later today along with pic's. We have been running there heads for some time now and have been very happy with the product and numbers!!

does this include STAGE 3 AFR HEADS? if it does can you shoot me a PM about them....i need a pair of AFR heads with (2.1, 1.6) valves, 1.55 spring, berillium seats, titi intake valves, and lightweight stainless exhaust valves....the heads will be going on a 402 cid turbo ls1.....(4.0 bore, 4.0 stroke)......So this works out great if they are on special...but if they arent let me know either way.....

thanks

Forget the lightweight ex valves..you want strong , heat resistant Incolnel valves. Just my 2 cents.

Jammers right on the exhaust valves. You are going to want to go with a strong, high heat exhaust valve. I will have a PM over to you shortly.

Thanks
