Ultra copper RTV makes gasket headache 0. Get a flange that wont impinge on the port, bigger is better...

Question i think this motor should have something like 30"tube,2 1/4-2 3/8 step with 4"collector. would a shorter header hurt tq? i realy dont see get'n a very long tube on this thing without going under the car like i have now. Smile

I used a doner set of bbf boat headers, found at the swaps for cheap, plenty of tube bends on them 2 1/4 "

the plugs are low in these heads so i think they'll work out.

i'm thinking i'll have problems with the torque,even with a short header. Laughing i've looked all over the bullet at headers and most are short but they dont have a lack of torque with all the juice...
You won't have a shortage of torque with that motor in the least.
