Which is better the shm full race heads or the dss full cnc ported heads both 2valve? http://www.seanhylandmotorsport.com/online/product_info.php?cPath=27&products_id=82 http://www.dssracing.com/ then you go to cylinder heads and click on cnc ported heads I dont know how to figure out the numbers so i just want to know how to calculate and which one produces more power.
I have seen a LOT of guys complain about SHM stuff lately I might stay away from them if I was you :dunno:
Neither... I did alot of research and talked to guys who actually had theses heads and the 3 companies i narrowed it down to were www.modularpowerhouse.com www.vtengines.com www.fox-lakeracing.com i went with the VT heads because MPH was out of stock.
I'm a little worried. I don't know anyone who uses or used Steen Heads. I haven't heard much about them... :dunno:
i didn't dyno after i put them on...i did some comp 262ah's at the same time. I went from a normal pi swap and could feel a nice difference but would have been better with a dyno tune.
I would stay far away from SHM in fear of getting ripped off. Buy your heads from anyone else.I would go with VT personaly because they are one of the best in the business and very reputable. Sean Hyland ripped off one of my good friends on cams he is a total POS. :aresehole:
i think if i bought heads i was looking at vt and could consider a set. do you know what power can i gain from just putting on those heads.
