Does anyone have experience running the Buschur Stage 3 head with the larger valves against an off the shelf, Wiseco e85 piston?

I'm concerned that the larger valve sizes may cause a clearance issue for me.

Call Buschur?

 

I believe Wiseco's are properly clearanced for most setups.

What cams are you using?

 

you're fine. the only time you have to worry about valves hitting pistons is if the actual physical timing is off on the vehicle by enough degrees to cause that interference.

 

Tomei Procam 280's

I'd call buschur but I figured I'd ask here first before I made a phonecall.

They typically use their own pistons for situations like mine...

I believe Tomei Procam 280's are similar to GSC S3's.

In that case, everything SHOULD work fine.

 

Tomei have quite a large lift. 11.5 to be exact.

I guess I'll find out after everything is ordered. I don't want to have to flycut these pistons or buy new ones.... But If i have to, oh well.

S3 has the same lift.

 

youll be fine they have the clearance for the valves just make sure your spring and retainers kit is good.

 

can you use max mivec advance with a buschur stage 3 head 0.5mm oversize valves and s3 cams, with 1400HD 10.5CR pistons? How can you check piston to valve clearance for max mivec advance?
