Diagrams are better than pictures!! :)

Thanks heaps. The Manual is very helpful if only I could get a kit to stand the engine up straight.

 

Thanks

A guy on ebay says his head has had 3ml out of exaust and intake ports is this even possible ? its a 4k head done buy somewhere called super flow hes calling it a race head but 3ml that possible ??

Link to add?

I can't find it.

 

Would probably be 3mm total diametre. so the side walls of the ports have only had 1.5mm taken off them which is entirely possible.

Just to add to this does anyone no of some were wich does cheap headwork ive been qouted 700 for head to be faced with 1ml taken of and a light port and polish

Read it right, just miss-undertsood what it meant. Yeah It'll be 3mm total.

Doesn't say anything about bigger valves though so the bigger ports are sort of just going to waste.

 

$700 is rediculous. I got a re-face and some porting done last year for under $400!!

yea thats what i thought thats y I'm looking for a used head with work done on it

I've done a few heads now. Costs about $100 to get a 3 angle valve job and the head skimmed if you supply a clean disassembled head with only the valves sitting in it.

 

Porting can be done easily yourself with the aid of a cheap dremel and a few hours work. I don't worry so much about enlarging the ports. Moreso a good tidy up. Remove the casting marks in the ports, narrow down the valve guide bosses, smooth the rough casting marks just above the valve seats, and blend the shortside radius into the seats.

 

Invest in some books by A. Graham Bell and David Vizard. Great stuff for hands on engine building and tuning.

100 thats hell good would be worth me sending my head to there and post it back insted of paying 700

I had this head port matched to a redline twin sidedraft manifold. Ports are about 32mm across, which is about 5mm meat taken out of them (don't quote me)

 

150 bucks with a light facing. Possible mate of a mate discount

 

u reckon ud beable to get it done again for around that price ill send u my head lol thats a good price would u beable to find out id be so very gratefull yet i don't have a manifold they can port match to
