there are different qualitys of WSM
i've bought several FORGED RACING kits and they are really top quality products , IMO even more than wiseco
they have a very good alloy quality and very strong design on squirts and axle area
i try to build all my engines with WSM now
can't say anything about cast one but the forged are top
strokersquid asked me "were to buy " i replyed something like dan at patriot or jeff at fast ....
but certainly wanted an instant buy on ebay so .... GR ....
lot of tuners claim to port the cubs - blablablabla - most powerfull cubs ---- blabla --
and some of them even don't remove the casting flows and sell them out of the box , full ported for what you ask , plated etc etc .....
if it s ported just get a degree wheel i ll tell you if it's stock or ported ....
me too , had a RZ billet head , with all rings , nice shipping and fast at the REAL cost , not *3 like some ebay sellers that sell at low price and add major shipping fees !
Thanks broke !
your set ut will depend on the porting you already have ....
4MM stroker changes a lot on the timings , so get your porting with a degree wheel or in height then put it here ..
And then you ll have the answer , basicly it s not possible to use spacers on a ported engine as you get too much timings on the exhaust duration ...
