What cam?

OK I really need HELP NOW.


I talked to Summit about the comp cam kit k20-222-3

They said i will need to mill the heads so the springs will fit. WTF? Is this true?
I didnt want to take the heads off nor did i want to spend extra money (which i dont have) on them.

My springs measure 1 3/8 (i think) and he said i would have to have it milled for 1 1/2.

am i over reacting? is this a big deal? does he know what hes talking about?

p.s. He also said the mildon windage tray wont fit my stock pan....Is this true?

I want to order this stuff....any help would be appriciated A.S.A.P

Thanks
