Has any body used the head with bigger valves and did you gain any more power and about how much do you think it was and are you happy with the head ? Odessa Cylinder Head sells one with a 2.02 intake valve and 1.62 exhaust valve , I would all so clean up the ports . thank you for any info you can give me .

I am old school and would always be more trusting to search out a good machine shop and have them go through my head vs a 'rebuilt'. I had a 'rebuilt' crankshaft snap in two on me once.
For the same money you can get your head tanked, magnafluxed, new exhaust valves and NEW springs and seals. Then vacuum tested. $545.

I did want to clean up the ports and run a set of roller rockers , I'm not looking for a lot .

This is normally what I did when I built both my stroker engines. Built a 4.9L (4.0L/4.2L/Ford 300 hybrid) and my 3.0L (2.5L/Pontiac/Mercruiser hybrid). The noticable difference was on the top end of the RPM range and both were Renix era, not ChryCo engines.

I have run a P&P head on other stock engines and got improved performance from of idle to red line , yes some were better then others but all did preform better . I was just to talk to some one who has run a head like I asked about .
