Porting small block 915 j-heads
Thanx for the reply Mopar official.
There are limitations with all cast iron head as we all know.
The T/A head had the best modification with the un-drilled pushrod tube!
The other side of this cutaway has been ported with a tube inserted down the pushrod hole.
You can then widen the port up to over an 'inch' wide and this straightens it up nicely too.
The 'Weslake W1' Big Block heads I have are unique, as they are bigger versions of the infamous W2 heads.
Ovalport intake and 'D' port exhausts.
Even more amazing is one head has 'cast in' guide bosses and the other has bronze 'race type guides that are prominent in the port.
But still a pair of very unusual heads indeed.
2.250 intake valves and 1.80 exhausts.
