Thanks for all the great advice!! I defenetly have a very good idea of where to go with these heads now....2.19/188 valves and a port and polish.
While i'm at it should i look at better springs?, rockers? any thing i havent thought of.
I'm on a budget but this car is a keeper and i want to do it right the first time.
Thanks for all the help again
If you are mechanically inclined at all, and competent with a grinder, you might want to save a bunch of money and port and polish them yourself. I just did my 781's at home with a couple carbide bits, sanding rolls, and an air grinder. However, many have used an electric grinder with great success, also.
For my first attempt at porting, I've received good feedback on the results. It costs big $$$$ to have a shop do it, and rightly so. I spent over 15 hours on mine. I got a smokin' deal on 2.19/1.88 valves installed and unshrouding. If you are going to go with dual valve springs, be aware that you need to get the guide bosses cut down to fit the inner spring. This was only $5 a guide, so not a big deal. I also went to the teflon valve seals at the same time.
My only advice to you is this : Get all the labor and material prices up front. You can get buried cost-wise in head work really fast. Before long, you'll be right up there with the price of a set of aluminum heads. Even without changing valve sizes, I was told you could gain anywhere from 30-45hp on just a good port and polish job. The only reason I changed valves was because I was offered a deal I couldn't refuse.
Good luck. If you want any pics, just ask.
