360 head porting for big power (500HP ?)

Nice work Skrews!

I've been a Big-blocks kinda guy since the 80's but a 'bad back' has made me 'see the light' with small-blocks.
Played with 318 (402) Poly's for a while and now got some 340/360's and 318's to build too.
We have all been seduced by aluminum over the years, but a shed full of IRON heads has got me thinking?
I don't have access to a machine shop now, as its closed down due to 'lack of interest' from customers.

So with all your ultra valuable advice and knowledge I will be 'porting crazy' during my Corona isolation.
Home porting with time/effort and little or no machine shop work...

Best wishes from the UK John
