I had to do this since my intake gaskets dont have a valley pan (Fel-Pro 1200's). I used a stock valley pan and cut it up to make a deflector shield for the PCV valve and used Epoxy to adhere it to the bottom of the intake manifold. The Epoxy will hold 3000lbs and withstand heat up to 250 degrees. Will this work for me ok? Does the manifold itself get hotter than 250 degrees? What worked for you? What did you use? I hope this way will work out because I already put the intake on! Thanks!
