Portmatching/Polishing 302 Aluminum Heads

Going from GT40P heads even if they are ported to aluminum heads is going to be a vast improvement for my performance plans. My self imposed budget is based on being a poor hot rodder which has caused the habit to stick. I'm starting with a set of Victor Jr clones that are bare "as cast". My initial inspection and evaluation of these is good to very good. There are defects as with any "as cast" product. The defects, parting lines, and other rough areas will be smoothed an blended to meet my needs for this project. It should take about 2 hours per runner. My time is much cheaper after retirement, I've found. The coolest thing is that I will be working indoors where I worked on my intake manifold about two years ago. It turns out to be perfect for this sort of job with lighting (ten foot window) and already proven work site. I have my magnifying light already set up. I purchased a HF tool that has a shaft and arbor attached with a 0 to 10,000 rpm control. The plan is to do this project over a loose time schedule when I feel like it so it won't become a hassle instead of fun. The build should be complete during the hot AZ summer and engine teardown and buildup completed before September and the beginning of the AZ driving season.
I have a couple of pics to show the tool and area. My plans are to have the engine checked on the dyno some time between now and HB. When I finish the head replacement, I will have it done again to see how well I did.
Wish me luck,
WEK. :cool::cool::cool:
