351w Piston To Valve Clearance Question

[sharp2377]

I have an 84 351w that currently has the stock style dished cast pistons, no milling. Motor was recently rebuilt. I wanted to switch my gt40 heads to edelbrock estreet 5025's with the 2.02 1.60 valves. I have a comp cams xe262h-h (35-238-3)with .493 intake .500 exhaust and a 262/270 duration. I know that the only way to be 100% that it will work is to measure it. But I don't want to order the heads and then find out the pistons need to be notched. Does anyone have an idea if I will be ok with clearance?

Notching pistons is easy and can be done in just a few hours. Do not let it hold you back. Order your heads.
