Technical Isky 400 Jr with stock 8ba heads?

Anyone one here running a 8ba with stocks cylinder heads and a Isky 400jr cam? I read that this would have some clearance issue? Can i clearance the heads myself if so??? Thanks

 

The valves will most likely hit the head way before they reach full lift.
Been over 50 years since I built a flathead with a 400 Jr, but IIRC, it took a flycut of .150" in the Edmunds aluminum heads I used. Ask around and you may find some old guy who still has the cutter and the setup fixtures required. I'd hate to know I was facing the job of cutting these out by hand on cast iron heads. Seems that I've seen some of the aluminum heads sold today that come clearanced for a .400" lift cam.

 

Swiss50chevy: The folks on www.fordbarn.com will have lots of info on your question.
They possess a ton of flathead knowledge.

 

had a 400jr in my rdstr, not very streetable, took it out, $100 if you need it.

 

Ill pm you.
