Thank you very much for the thought out rather than canned responses. I really appreciate it. As far as the ebay header, I was thinking that I might be better off with a stock dual port exhaust manifold, but Im going to try this ebay header anyway... The ports arent overly large. I might even wrap the header and uppipe. Im trying to keep costs down, lol.
The cams....Im trying to "run what you brung". Back in my Honda days, I used to run big boost on the N/A cams all the time... DOHC ZC's and SOHC D16A6's. They made really good power for their size, and with 20+ psi I never noticed any problems with power falling off at the top..The only thing that really throws me off is those offset exhaust lobes on the EJ25D cams...
