ya i have some insight, send your damn cylinders out already. I know you gotta learn somehow, but i dont think reading a couple books and grinding away is your answer. You need to go to school, or find someone who has been in the biz for awhile and let them show you the tricks. Just because i read a book on regrinding camshafts and porting cylinder heads for small block chevys doesnt mean im going to attempt it. Your essentialy doing both, which can be very tricky. Trust me you will be much more happy sending your cylinder heads out and getting them ported. If your already contemplating using epoxy then your making mistakes. Trust me i never like to send anything out, or have anybody touch my stuff, i rebuild my own automatic transmissions, engines, manual transmissions, etc. But porting is a ART and im not that talented, and dont have anybody that talented near me to show me the tricks.
Just my two cents take it how you will
