hi allen its paul.as you know i just fitted the 48 idas to an identical engine. i had greatb luck and and instant seal with the permatex hylomar on the gasket ports and the right stuff on the water ports.
it is imperative you have jim send your intake maifold out to cobra automotive to get portmatched to your heads. try to contact your head manufacturer for a cad drawing , cobra automotive prints this to scale to use as a porting template.i used a thicker SCE large port gasket ...perfect fit for my 205cc intakes.
You will also need to remove an inch by i inch piece from your bellhousing[if you have an aftermarket] to mount the throttle pivot....a noisy messy job with an angle grinder and cut off wheel.
make sure you use studs in the heads. You will also need to make yourself a cutoff open ended wrench in order to tighten the center nuts under the carbs.
before you lower the intake fully with the glue tacky , put a couple of wood blocks under it to hold it off as you need to start the nuts under the center
carbs , they are impossible to get on once the intake is fully pushed down.
Jim did a great job with all the linkage and carb prep.
Many people dont realize he goes through every carb and blueprints it to your spec.Its very important to fit his low pressure regulator and make sure you have a high volume low pressure pump.Webers worked best at 2.5 to 4ilbs , mine are at 3 ilbs and perfect.
after a bit of synching with the synchrometer i adjusted the timing to 34 degrees full advance.....its spot on .My car fired up first go.
my car dynoed at 504 before the webers and we just pulled 543hp on a 347 stroker with the webers....yikes!!!!!!!!!!!!!!!!!.
everycar is different but i hope these tips find you well.
p.s. i also fitted the avon tires ....they have to be the best tire for a cobra but sadly very expensive..!
