Not very often (never!) That I can offer any insight.
I put KB167's in my 318. Six of the deck heights came out at zero and two were a couple of thou down. I called that good.
I would do the mock assembly and hope you are as lucky as I was.
Hi,
They are stock 318 heads, can't remember the number as it's late and I've been drinking lol.
It's just a quick-ish street motor.
Cheers Paul in Northamptonshire
Thanks YR.
I've done a few heads over the years but the gap in-between is usually a long time. The last set were a pair of d0ve Ford heads for a 460 about 15 years back!
I used burrs on the 318 heads, as you say practice is key. I have an air die grinder so speed control is easy. Getting used to...
I'm not sure what to take from that.
I haven't changed the port design. This is very much a take on the thread OP's postings i.e. open the bowl and knock off the rough edges. I have not touched the SSR other than to blend the rough transition to the seat. The port is stock from the guide out to...
They are 675's.
What would you like pics of? They are not the prettiest examples of porting, I don't claim to be any good at this!
Probably be tomorrow now.
I did my first exhaust port. I cut the bump down as far as I dare, it's just a very slight rise now.
Bowl is opened up and all edges blended in. The black area in the photo is a divot in the casting.
After not finding water (hurray!) I completed all the ports.
Thanks rumblefish. I can't seem to find a definitive statement on the exhaust port bump so I will be cautious. Plan is to smooth it out and call it good.
The bowl shown is opened up to 89% of valve size give or take a tad.
Thanks guys, appreciate the feedback.
I didn't go too mad. The short turn is untouched apart from blending in the ridge in the bowl and the pushrod hump is likewise untouched.
I thought I would make a start on porting my heads loosely following the sticky guide.
This is my first port (on a 318) so any comments/feedback would be welcome.
One question regarding the exhaust port. Can I remove the hump on the roof completely or do I risk water?
No more photos at the...
