351W DO0E HEADSWAP HELP
I have a set of 351w heads for my 1990 GT.
They have been RACE PORTED INTAKE SIDE, RACE PORTED EXHAUST SIDE, 1.60 EXHAUST VALVES, 1.94 INTAKE VALVES, BOWLS ENLARGED.
I need to know with stock cam and 1.6 roler rocker ratio (stock length) , do I have to worry about piston to valve clearance, or is this a direct bolt on and will clear the reliefs on the pistons?
also my email is apo2p@yahoo.com I need to know soon,

I know I need washers to mount the 7/16 bolts in the 1/2 holes etc.
I need to make sure the heads and bigger valves will not hit the pistons.
]The second thing is that I am installing a racing compressed head gasket, will this effect piston to valve clearance? or not?
