what parts will inter change? having an idea to stroke my 129 in my to30. i want tot keep orignal block if possable. is the 145 head the same as a 134 head with bigger valves? z129 can use 134/145 mains, so will the crank also inter change? piston rods are the same.. if u order a new cam it says it will fit all 3 engines. if i use a 134 head on a 129 do i need the 134/145 rocker assembly?

Well for starters you can't install the head from a Z145 or Z134 on a Z129 block. The coolant by pass holes are different as well as the number of studs are different with the Z134 and Z145 using more studs. It will physically fit but that is about it. The 3 3/8" sleeve is as big of a sleeve as you can fit in the Z129 block. I wouldn't try to boost the power in a Z129 by much...they can't handle much more power than stock. That's why the Z134 casting has more reinforcement in the casting.

Be carefull with the cam, dist drive gear count is different on the 145, dist gear has different tooth count also.
