RV-4 conical engine mounts

I am changing engine mounts while I have my engine out (0 320 B3A) and want to use the Lord mounts as replacements. Can any one tell me what are the best ones to use ?..
J-6230-1
J-9613-40
J-1552
J-6113-1
Any advise based on experience would be appreciated.
Thanks,... George

George,
I have Conical mounts on my 0-320A powered RV4 and more recently on my 0-360J2A powered RV6"X".
Years ago I used Vans mount rubbers on my RV4 and have used Lord mounts on other applications (expensive) but later replaced them with these from Aircraft Spruce.
Less expensive and work very well. I used the same ones 10 years later on my RVX. The best?
Check out my PS below...

PS: The best I have seen though are the ones on my current Sonerai II from Rev-Master....The VW conical and Lycoming are identical. They're polyurethane instead of rubber and don't deteriorate as quickly and will fit a Lycoming. They're also cheaper...

Thanks Smokey,
I definitely will check those out. The bushings I took out were shot. probably original.... The bottom left bushing , which carries all the weight of the engines left side, wore completely through.!.. Polyurethane sounds interesting in regards to its heat and oil resistance...
Appreciate the info.. Happy flying..... George
