more pics and "stock heads over after market heads"

Some more pics of "Britains Fastest Van" being built. Engine is currently stripped and being fitted with heavily ported stock heads amongst other goodies new kieth black 116 pistons and a comp xe268h cam any of you guys using a 289 with mods? *** Ive been looking closely at some after market heads this week as im looking to upgrade the power output of my 289 ford hipo engine,I work on the philosophy that if you cant make it or modify it then steal it or buy new! But only as a last resort!!!

The heads ive been looking are edelbrock RPM,trick flow and afr"s.My own stock heads are 289 ford and have come to the conclusion that 1200 in UK for a pair ( minimum ) is not good value for money. Comparing the inlet ports the size and shape is exactly the same as the stock ford,combustion chamber shape and size the same,valves in the aftermarket heads are bigger but are not always necessary,some people over valve their heads leading to sluggish bottom end response and poor vacuum,the only real difference is the exhaust ports being that on stock heads they have a very poor flow rate caused by casting lumps and badly designed shape,this can easily be rectified by a simple porting job,so what are we paying for exactly,the fact that they"re made from aluminium? big deal,the fact they have huge valves,big deal,the fact they have a 5 angle valve job? big deal.
In my opinion a set of correctly ported standard heads which will cost you about 58 for the dye grinder/stones and carbide burrs, matched to the correct pistons and camshaft are as good as any after market heads ( in the case of a ford windsor v8 ) that is,whats your opinion and experience???
