Setup for 273

thats Sounds so easy but Its not that easy to find a Set of heads here in Germany.
also i Need the commando heads with harder valve Springs.
for this Reason i bought the easier aviable 318 heads.

if I find no heads or rocker cams i will use hydraulic lifters and just mile down.

Are there any issues with the solid e4 cam and hydraulic lifters ? cheers
No you shouldn't run a solid lifter cam with hydraulic lifters.
