Re: Information Wanted:
with no piston reliefs its important to measure piston protrusion and factor the 'quench' (the distance between the head and the piston at TDC)@ .040 ideally. Model A pistons can protrude above the deck of the block at TDC up to .040..with no piston reliefs cut into the head like your super,the piston can strike the head if your not careful..the easy way to fix the issue is to fly cut the head here's a fly cut 6 to 1 winfield aluminum head..a machine shop 'fly cuts' a relief for the top of the piston..
