Porting small block 915 j-heads

Hi Kma,

Hope the weather is good in Sweden as its super here in Kent UK!
I have the sliced up 'J' head (from Weslake Eng.) and its very different to the later heads, in the waterways?
Was wondering if the castings were the same internally but they is totally different indeed.
I will take some pictures for you tomorrow.
That later stuff looks real bad for porting to me???:wtf:

I have a pile of late 360 heads that have problems, coupled with bad castings so I only go with 'J' heads as they is super!!!
I have several heads and engines from the Weslake Engineering shop here in Kent England.(closed down in the 80's)
They were employed by Mother Mopar in the late sixties, early seventies to 'refine' head castings for NASCAR etc.
The Weslake 'J' head I tried to copy in the past but always went into the water jackets when 'TRYING' to making a perfect twin!
So now I have done a 'nearly' copy to stop wasting many hundreds of hours on SCRAP!
I suppose the 'Weslake'-'J' head was a new casting in 70/71 without the rust issues of the 50 year heads we have now???:drama:
