Small update on the until.
We have electrical supplies fitted for welder, compressor and head skimming machine that’s now been moved into position.
Floor painted and will need an another coat after 3 days.

Just need to do a bit of planning to see where everything else will go.

Well happy with the transformation with the before and after.

Throw back to when Terry’s engine went big time at Santa pod.

At the time it was a Blacktop Zetec running about 700/800bhp I think and had done quite a. Few seasons and dyno runs with no issues but with all things modified they have a shorter lift span.

EDIT:
Showcase your engine explosion’s.

2.0 8v Volvo ( Renault )engine all built and done. Custom higher compression pistons with deep valve pockets will make sure what ever cam is thrown in this engine it will have plenty of clearance.

GT4 heads looking sweet with the 5 angle inlet and a 2 angle with a radius ( didn’t take a picture ). Just need to skim when new cutter comes in.

Working on the GT4 heads and in preparation to giving the seats a light cut, cleaning up the valves I’ve taken some measurements of the valves and throats to find that the valve to throat percentage is 85% of the valve so there is room for improvements if anyone wants to get the heads ported. The average joe would look at them and they they are amazing as standard but that’s not true.
No pictures but we found a few of the valve stem seals had come of the guides. Some new exhaust valves and seals will be fitted after cutting the seats and both heads getting a light skim to make sure they are 100%.

Porsche GT4 heads come into the workshop today. No porting to be done but just general repair with new valves to be fitted and cut seats.

I would love to have a go at porting these heads. Might as well get them on the flowbench to see if or were they can be improved.
