318 head porting for the average joe

There is always a danger of 'hitting water' in any port!

The other side of these 'bumps' is a mirror image in reverse.

Going thin in the port roof will always be a disaster in any 'iron head'.

Especially when the gasses are at 1000 degrees for hours on end, on the Freeway...

But if you are like me, its just grocery getting and once a year 'at the track' then we are less worried?

A 'UK pound' for a mile of travel is hard on the wallet!
My 452ci engine was worse at £20 every 'quarter mile'...(C12 race gas '£130 for 5 gallons' UK 19 litres)
