I can measure the set I have, or call Mike at TA, he might tell you? The ones I got from TA didn;t work with the Block I was building. The center two long ones were too long and interfered with the rocker stand. I ended up using ARP bolts in those two locations on each side, 'cause that's what I had in the shop. All of the studs under the rocker stands on that combo hit the underside of the stands. I eneded up machining the recess deeper. Just measure the length you need at each location and call APR, but I don;t think there is a kit that will work? You can call ARP and ask. Seems like every part for a 700+ HP engine (regardless of brand) needs some sort of tweaking. The oil pump adaptor (external feed one) needed ALOT of tweeking to make work. I'm sure Mike has that sorted out now.
