p/v clearance? non-ho 5.0

[z2o_what]

i bought a 5.0 out of 87 lincoln town car, assuming that the pistons had valve releafs. but after pulling the heads i find out they are dished with no releafs. to my suprise the engine has a roller cam .

so..... can i use d0oe 351 heads (stock valves) with a tfs stage1 cam without clearance issuse?

should be fine put the cam in and bolt the head down with out a gasket and put some clay on the piston and put rocker on the intake and exhust valve and spin the motor over by hand pull the head off and see if it touched.
Why would u run the dished pistons for anyway? Unless you are running a blower.

my 86 short block had flat tops, so i got another engine, thinking they would have releafs, but they are dished.

i guess if i have problems i'll just run a tick head gasket and a shim
