SM Head Modifications on a budget

It wouldn't be a bad idea for you fellas to discus and form a list of porting areas to do from first to last. (or us street guys that just want to tune up a set of heads but don't need or can use maximum flow for big horsepower)


That my friend is what this post is all about. It’s super hard for me to flow test every single thing I do to a head but he is being gracious enough to do so. And probably learning during the process. I know how to get 290 out of a 2.02 valve, and 312-315 out of a 2.055 valve, and 330 plus out of a 2.08 valve. But during this test we are testing things guys can do at home and probably send it out for a competition type of valve job. If we could find simple things a non head porter could do at home and get 285-290 out of it I think that would be great. Probably a hard target to hit but why set your target low.
