Porting small block 915 j-heads

I kinda missed a time period and I think I’m both happy, and sad about it. In the 1970’s early 1980’s I manly street raced because we raced all week. But on weekends I did run a best of 11.82 when at the track with my 340 and ported stock heads. Then I hopped into big blocks. After my wreck in 2010 I jumped into the seat of the black duster I bought but my son was racing. Edelbrock heads were everywhere plus I got one set with my duster. They were so easy (and clean) to work on so I continued to do so. A nicely ported set of stock cast iron heads can be a beautiful thing in the right hands. And run great too. Keep up the great work guys.
