MODIFIED SPRINT CYL HEADS

[ALG1K]

Just a couple of questions<br>
Has any one had there sprint head modded <br>
Ie gas flowed <br>
If so who did it and what were the qualifications <br>
What did they port the intake and exhaust ports too <br>
Ie what size mm and why did they come to those sizes<br>
What were the works race cars ports taken out to <br>
Did they fit larger valves etc etc<br>
Im intrigued. <!--EZCODE EMOTICON START 8o --><img src=http://www.ezboard.com/images/emoticons/nerd.gif ALT="8o"><!--EZCODE EMOTICON END-->

Not much room for larger valves, but the F3 heads had slightly larger ones. Whispers: I've got one in my garage if you want to come round and measure it.<br>

No idea what sizes mine are, I suspect standard valves. A place in Coventry carried out the work under Jigsaw.<br>

It was probably ACE Andy chesman engineering that did your head,<br>
Im going to gas flow a sprint cyl head <br>
I have done a couple in the past but i now have the use of a flow bench and have learnt quite alot doing these cosworth heads not all turbo heads <br>
Im also going to be fitting big valves as im sure this can be done by using offset valve guides ,removing the original valve seats welding the head up and machining the seats slightly offset to the originals<br>
Then all i need is a engine to try it on.

ive gone down the same route as scott, not sure if there was any difference to the specs of port sizes etc, although im on DCOE 45's and scotts on DCOE 48's.<br>
<br>
I have the spare engine for my toledo resting in hinckley if you need to boro it, and maybe accidentally leave the mod'd head on when it comes back...<br>

Darren, just build me a mental race engine. You know it makes sense! I might even be able to pay you for it!<br>
<br>
Seriously, if you wanted to try the head out on mine, we might be able to do a R/R run where I had mine done last time and compare the results.<br>
