I have heard that you cannot run anything bigger than a 1.94 intake without notching. When Edelbrock first released their heads, that is why they had two identical heads with different size valves. One was bolt on and one wasn't.....
One thing you could do and still run them is to open the intake reliefs up with a dremel about .030" or so. Pretty easy to do. Just lay duct tape across the whole deck and piston with the piston at TDC, with a small window cut out where the pocket is. Dremel the pocket. Then vaccum up the chips and repeat. The exhaust side clears fine.
Another funny thing: Don't always believe what the tech guys tell you. Most of them are just bench racers and never have actually built anything before. I used to work at World, until they moved. One of the phone tech guys had to ask one of the guys in the shop to help him check his anti-freeze because he didn't know how.:lol: And this is the same person on the phone giving advice on head and cam combos, etc. The same people that write the head instructions. 99.9% of the time when you call, the are just reading notes from a book.:lol:
