*so there i was at 11pm and i decide to set my engine at TDC to set the rockers and low and behold my valves are touching my pistons when i bar it over. i have 63cc heads with .040 cometics, flat top pistons, 1.7 roller tip rockers and my deck height is stock. are my head gaskets to thin?

Cam 228/234 .588/.595 112 lsa

 

It is possible but are you sure the cam timing is set correctly??? Are you sure you have the correct length push rods???

 

Is this a stock replacement piston or forged??? You mentioned stock deck height but not what piston. Also did you check to see if was out of the hole and by how much??? Is this stock or stroker build???

 

i have a similar setup with 59CC heads on higher lift and i have no issues.

 

They are flat too forged Manley pistons

 

And 7.4" pushrods

 

check the cam timing. OP, which casting head how much were the heads milled to get 59cc.

 

They are 63cc and I'll double check my timing tonight when I get home

 

with the heads removed it still will not turn over. im thinking its the windage tray. will pull pan tonight and take a look

 

You shouldnt be having this problem given the information provided...
