intake center bolt question

[sweetk30]

i know the older intakes were all the same. but tbi and newer the 4 centers were changed for the hold down angle.

didnt someplace sell special washers for this to let the bolts sit flush .

of do you know the 2 diffrent angles.

ya ya i know just hog out the holes and be done with it. but i dont like to as it is to be done right 1 time and forget about it.

thanks.

McMaster Carr sells the spherical washers but you still need to elongate the holes and there isn't enough material for the washers to sit properly once done anyway so i wouldn't worry about them. Once you elongate the holes you can then use a grinder to change the seat angle and you'll be fine.

The intake ports don't line up correctly either. If you want to do it right, get the right intake.

You are thinking of the Vortec ports, but the bolt pattern on those is entirely different.

Yeah, my bad.

one trick I saw...

I saw one guys 350 that he put a carbed intake on, by hogging the holes out enough to get the bolts in--then he used a 1/2" drill to "countersink" the intake holes some,and he used old rocker arm balls as conical washers!..I thought it was a pretty good way to do it..
