K Line Valve Guide Liners.

Having been reading Des Hamills Book How To Power Tune Rover V8 Engines, my other Christmas Present to myself, I was interested in the section on valve guides, Hamill recommends having the Bronze spiral grooved liners installed rather than replacing the whole guide, this is related to my Buick 300 Alloy heads and being 42 years old it seemed a good idea not to impart any unnecessary stress on the heads by boring out the old guides and press fitting new guides.

Anyone have experience of this product and know a company in the south east who can install them.

Hamills book is quite a good read, somewhat light in certain areas but if you want to know about liner problems in the late engines worth the cost just for that. In a nutshell don't go near 4.0 blocks as these engines were assembled from second grade blocks.

I agree that its a bloody good read. His thoughts on cam duration are a little worrying to me, I think that he regards a seat to seat duration of 270 to be quite radical. My typhoon is 320 seat to seat

(Its 220 at 50 thou).

What size engine are you running and whats it like off idle to 3000RPM.

I'm thinking of using the Typhoon in the new 4.3 engine I have a Hurricane in the 3.5 at the moment, it's pretty smooth at the bottom end and wakes up at 3500RPM and the engine starts to sing.
