Will .8 compression really make that much difference??


Yes - Look at this thread earlier - they tuned the DBW engines to make up for power loss.

I reckon 2 or 3 bhp minimum would be found but also better mpg


Is it worth it, for a barge?


Given the additional cost is small and only involves time (your won)......then why wouldn't it be  :y



I am buying a spare pair of heads to refurb so will be investigating skimming very seriously.

Will be porting too. Years since I've ported.

Done a 33% improvement on a 100cc bike and 66% improvement on a Hillman design push rod lump

Ok, stripped a head down today.

Here is a pic of the trouble stem seals.

The green one is the standard Vx stem seal as used throughout the 2.5 and 3.0 production run plus most of the other big block 4 pots to!

The red one is the issue, it is vey hard and I could simply pull it off the guide with my fingers (compared to the ones on TB's old heads which required special pliers and brute force to shift even at 10 years old and 100K+ miles).

Now these came into existance because some low life, sorry purchasing person, decided to try to save a penny a seal by using an alternative which had not been proven!. I trust they were sacked, fired and buried for that one!



Here are all the removed items, these will be soaked in caustic soda for 24 hours before having a good hot rinse and final clean in an ultrasonic bath.



And the head, this will gently 'bleed' old oil until I get a chance to pressure wash it down ready for a bit of 'touching in'

Surely you could get parts sent from the UK much cheaper than that.
