A little something we have been working on.

ATK will be offering a full line of SBC Performance Cylinder Heads, with BBC and SBF to follow later on next year! These heads are 100% Cast, Assembled & Machined in the USA!!!

I was at the foundry the last 2 days looking these over with our Guru Mark Johnson. We finally got the samples done and it came out exactly as we wanted it. A high quality, great flowing, user friendly, american made head.

I hope to have these ready to ship after SEMA (we will have the samples there). They will be available in 64cc/70cc combustion chambers and 185cc/195cc/210cc Intake Runners. They will have 2.02/1.60 valves, stock exhaust ports and setup for Hyd. Roller springs good to .650 lift.

We also plan on being very competitively priced in the market, trying to come in at $1150.00 a set! :thumbsup:

This is our 64cc/195cc SBC Head as Cast ports.

We are looking at a 290cc and 320cc as this is what we will be able to use on our crate engine line as well. In the future I foresee this growing into some better flowing larger intake runner heads. The heads will be an Oval intake port and we are going to try to make these as easy to work with as well with Stock exhaust port location and will allow the use of an off the shelf intake.
