I am planning to buy my own billet heads at september-october.
I have been in contact with Elmer Racing and i like their quality, good communications and relatively fast turnaround. Also they have experience on cylinderheads too. Heads at the pictures are from OTHER company.
https://www.facebook.com/ElmerRacingDotCom/Only problem is that i would need order atleast 3 pairs of cylinder heads at same time, to get the price for pair under 2300€. Obviosly 4 pairs is cheaper
They do accept 50% payment before payment. Heads can be paid to them directly with Paypal or Moneytransfer. If you are not EU citizen, i can ship the heads to you
Heads accept up to 54x40 valves with Pauter rockers, because valvecover flange is littlebit different than at stock head. I can offer either bail or bolt-on billet valvecovers at 295€/pair.
All heads could be made with different configurations. Port sizes have been calculated and ports have very little work to be done after seat installation.
2mm thick coolingfins with 3mm gap look very good.
Ports have good size short side radius and very little porting to be done. At end of this year, heads at pictures will go the headporter to get finished and for flowbench testing
