[j2a2ndo]

alright im planning on doing a lsvtec
i have a ls block with ctr pistons on ls rods and stock rod bolts with gsr head bolt and gsr head wit dual springs and retainers. will i have to change rods or rod bolts or will it be good like that

[mannyfresh860]

definitely replace the rod bolts
just get ARP rod bolts and the head studs while your at it
