I think bigger ports... smaller valves... higher compression when bolted on a 3k. lots of info on the FAQ on this I think.

 

I think that this combo will infact give lower compression, and is why it is used by

some for forced induction setups.

 

Also, I think taz was observing that the ports on your 4k look bigger than the standard ones.

 

Will be keen to see this car out and about :D

don't be confused by the rocker cover.. I had already swapped the rocker covers by the time I took these photos.. so 4k was K.. and K was 4K

I see, that make sense :D

Sold to a good home. Going to be restored by an older guy as his hobby, which is the perfect result I reckon. Thanks for everyone's thoughts on the car, I will miss it!
