I decided to start another thread focusing on purchasing new heads, my other thread was all about compression and narrowing down what I truly had and I learned its much higher but with the opinion and facts brought to my attention I was able to speak to the right people and will be using E85 and simply run this motor, my current heads are small 185cc intake runners, they also need some work so I would rather invest into something new :thumbup:
My 63 nova will be 80% street 20% strip, its a gasser and will not be used in Road courses or speed runs just street/strip
So this is my full setup
404 SBC 4.145 bore
13:1 compression w/64cc heads 12.8:1 66cc -- 12.5:1 68cc -- 12.2:1 70cc
TRW pistons, Eagle Rods, Forged Crank, Internal balanced
Weiand Tunnel ram with 2 horsepower innovations 650 E85 carbs
4-speed M22 ( soon to be ordered )
4:11 rear with 28" tall tire
Car weighs around 2700lbs
Cam 296tls6 http://www.summitracing.com/parts/cca-12-517-5
Any info you can provide would be great, and if I need to add more info just ask !!!
My few questions that come to mind would be purchasing an assembled head, lets just use Product " A " as the example. Product A has a max lift of .600 so would that automatically work with my cam that has a lift of .570/.580 ? Also the quality of valves in an assembled head ?
Or would it be wiser to purchase a bare head and drop it off by our Local head guy so he can order springs/retainters based off my cam for more of a exact spring lb. rate ?
Aluminum or Iron, knowing I'm using E85 would Aluminum be too cold with the burn rate.
Our local head guy Likes Iron heads as well aluminum, also speaks highly Dart and of Howards springs and overall head products. He has nothing on Aluminum just says its his preference is iron.
Thanks much !!!
