I know this might be a no brainer for some but GT40Ps or iron Windsor jrs? I know a lot about the Ps but don't know too much about the windsors, I heard though that they outperform GT40s and have a lot of room for improvement with porting. Let me know the pros and cons.

if you plan on a header purchase at the same time, go for the GT40Ps.

Windsor Jrs I'm sure flow better and utilize factory type/plug angle headers

I already have Mac equal length shorties on my car and from what I hear these work with the GT40Ps.

Yes, they'll work. You may have to modify the plug wire boots, though.

I would say Windsor Jr's they will also allow you more room to grow, properly ported they can make good power

The windsors are gonna cost me about $450 from someone I know. Thumpers will cost about $700 and I would pay more than maybe $300 for the GT40Ps.

I got Windsor Jrs ....i got mine on a complete longblock from my friend...brand new 1.6 rr's, billet flywheel, like new clutch low mileage on the motor, Lunati cam, timing gears, chrome oil pan....all for $450

My vote is for the Windsor Jr's too....BTW they come with SS Manley valves from the factory and have 2 different header patterns for im guessing bigger headers?

Anybody have any specs or info on these heads? i would like to know more about them...valve sizes, flow numbers or anything
