Default AFR 185 piston/valve clearance issue?

I have heard that because of the huge 2.02" intake the angle of the valve that the AFR185s intake valve will tap the piston. I am not sure of this or heard of any kind of comfirmation that this is the case with my year and stock cam.

but i did come up with an idea, if in the case i get the AFR 185s and need to install them because this is my daily driver, could i perhaps decrease the valve lift by getting 1.5 rockers just for now so the car can be driveable? what would be an easier solution? IF there is valve/piston tap at all.

i dont think you have problems with clearance, unless you go up in cam size.....

get out your dremel and open up the reliefs...take cotton and run it around the piston to hold shavings then use a shop vac to pull up the cotton and shavings..nothing to it..takes about an hour

i would be reluctant to do this because if i dont remove the same exact amount of material on each piston the rotating assembly will not be balanced anymore. i think increasing the depth of the reliefs should be professionally done and in that case i dont wanna pay more for that!!! does anyone else have first hand experience with the AFR 185 heads and a 5.0???

it this engine balanced?..if it's a stock rotation it isn't even close....where not talking about all on metal..don't be sheeerrrd to do this...1.90 valve is all your going to get on stock pistons.....

If it's your daily driver I'd suggest 160's anyways.
