Porting small block 915 j-heads

Back in the day if you wanted to run a TEN, you needed an Bigblock here in the UK.
Now I see guys running TEN's with smallblock stroker's and even NINE's ...:steering:
Yes Aluminum heads were around but us 'Dynosaws' loved doing it the hard way, with IRON!!!
Porting skills are a dying, if not 'lost art', so we just like doing it for fun, especially in lockdown...:thumbsup:

If we ever get to use them on the track or in the Boondocks again is another matter???:confederateflag:
