Don't know where you are buying your studs and guideplates, but ARP studs(the only brand I buy) and any guideplates comes to $52.00 or so from Summit(for example). We got our heads from Shaver's in California while they were still ProTopline but have since been told that the EQ iron heads are the same casting (the earliest EQ ads even said so), and you can't get aluminum from EQ, only from RHS.
A quick clean-up with a cartridge roll to remove the lip left by machining that is under the exhaust seat and some slimming of the exhaust guide boss brought the exhaust numbers up quite a bit. There is no such thing as a ready-to-run aftermarket part!! (unless you pay$$$$) The sooner everybody learns that the better.
We are using the 235 Runner 2.08 intake valve 64cc chamber on an 11.25-1 383 w/solid roller, etc. Runs mid tens easily at 3500 lbs on drag radials. We are happy with them, and would buy another set without a second thought.
