Hi,

I've got some FD housings from a guy who said they were ported well and that I shouldn't go much bigger for street usage.. Because I have not much experience in porting I'll post some pics..

They things I already got: make the closing line convex and very smooth to support the side seal, polish the runner, don't cross the oil seal line,...

Those ports don't seem to be that big, do they?

Any suggestions are welcome!!!

Thanks!

Should I resize them to 800*600?

But yeah, my cam can go a little higher if you want them bigger https://www.nopistons.com/forums/pub...DIR#>/cool.png
