So my problem is running afr 185 heads on my 306. I got these heads with the planning of having the pistons notch. So the machine shop that was going to do this move the price from $150 to $450,I don’t feel like paying that much. So I was just thinking of selling them or trading for afr 165 heads or twisted wedge heads. So what do you guys think I should do?

Do the pistons have to be notch with twisted wedge heads or afr 165?

btw my intake is the eddy rpm 2

1)trade the heads for afr 165 or twisted wedge heads
2)get the pistons notch

Thanks

Degreeing the cam would be nice for some more power, but it's not necessary.

I would use a pushrod length checker to make sure you get the right length. You might get lucky and find out your stock ones are okay, but better safe then sorry.

Are you using pedastal or stud mount rockers?
 
Degreeing the camshaft will help, IF your camshaft is off to begin with.

When I installed my custom cam a few years ago, it was dead on.

Luck was on my side...

Degreeing more-or-less confirms if you are off or not. If you are off, make the adjustments necessary:)

Good Luck.
 
You can get a camshaft with valve timing events so it will clear, but I hate to see an engine being restricted by the radial of the valve on a 20* head being the reason for the camshaft.

You can not get 100% results this way, but it can work nicely if done right.

A 20* valve angled head with a 1.90" intake valve does give more radial clearance.

I think it has more to do with the cam designer than luck. When I got mine, it was also dead nuts on.
 
I also wouldn't replace the 185's. You could remove the valves and use the heads as a guide to flycut the pistons yourself. You just set the depth you want to notch them, set the clamp, chuck it in a drill, and start cutting away. Check out this thread in 5.0 Tech for more info and a user testimonial about the Isky tool. Here's a link to the tool on Isky's website, too:

In my conversation with Jay, he told me that noone can guarantee a camshaft that is not off.

That is why he likes to "cam doctor" them:)

A Summit degree wheel will work. The larger, the better.

I really prefer an AFR 185cc head with some aftermarket pistons, so the valves are not a factor to work around. But, I agree with the other guys - I am not sure you want to get rid of them.

They can be useful now and later.
