connect ls2 coil packs to my ls1 wiring harness

[jeep pit]

hi im doing a ls2 head swap to my ls1 and am wondering if i should purchase ls2 coil packs and connect them up to my harness as the valve overs are different a dont allow me to use my ls1 coil packs or should i just make up a adapter plate to allow me to use my coils ? if an adapter for my harness is even available ? thanx guys

why can't you put your valve covers on the ls2 heads?

My VZ LS1 which had standard 241 heads had everything was swapped over onto the 243's no dramas

did u have them ported ? did u gain much
im havn mine cnc ported , stainless valves , titainium retainers ect
im just not sure on the inlet manifold yet or which type of extractors to use 4> 1 ... 1.75 inch or tri y as mine is an auto and dont plan on using a stally with my cam selection

They were already ported when I had purchased them

Keep the inlet manifold you have, with extractors tri-y are good for low down torque and 4-1 move the torque range higher in the revs, See if you can get a tri-y with a 1.75 primary this would be optimal when doing the mods your planning

What cam are you going with?
