Since you are only changing the shortblock, yes it will work fine. However just be ready to compensate as those pistons may raise your compression ratio a bit. But I cant give an exact number based on summits description.

 

PACE Performance #12556121 SPEC's ARE
SAME Shortblock Used With #12568758 & #12520270
(1987-1995 Truck Engine) & 1996-2000 Chevy & GMC Vortec 350 (Vin Code R)

When used with 76cc heads compression ratio will be 8.1:1
When used with 64cc heads compression ratio will be 9.1:1
When used with 62cc heads compression ratio will be 9.2:1
When used with 58cc heads compression ratio will be 9.6:1
