Porting small block 915 j-heads

Nice work Moparofficial!

Happy New Year from a porting Limey lol.

I read on another site that the 'X' head is better than the 'J'?
They prefer them to the 'J' for Superstock (back in the day)

Whenever I do the port floor I get all nervous and anxious about a break through!

This is the template I use for max flow lol...

The curve is actually 2.02" drawn around an intake valve approx 1.00" high...
