Will old style A heads work with flat top pistons?

Hello Jon ,
will the old A heads just bolt on a motor with flat top pistons? or are the valve angles to far off? Thanks.

Not Jon, but they'll bolt on.

Now in regards the valve notches, if the pistons are for standard, stock style heads, you'll need to either:

a) Put new valve notches in them.

b) Get new pistons.

And yes, they have completely different valve angles.

Hope that helps,

Dave

My first set of a heads I cut the valve reliefs in the old pistons by putting a cutter in the guide and put the head on the motor and using a drill cut the reliefs ,maybe not the best way but it worked .
