Ginge - you put a post up last week asking what something was that you could see through an inlet port, and didn't realise it was a valve!

I'm not knocking your drilling ability, but if you fuck it up, are you gonna lay out for a new block?

Since you're also so concerned, my track car build is going very well thanks. The difference is that I like my stuff done properly, so it takes a lot longer and costs a lot more.
