If you have a GT-40 intake and need to go with a 1" phenolic spacer READ

[Mike Souslin]

I have a 1" spacer on my car also but it was out of necessity for me. With my heads I had to use the spacer for the upper intake to clear the rocker covers! I do have a very small dent in my hood from where the TB is hitting it when the motor torques over!
The cowl hood will solve this problem in the future!
